Answers
Answer:
poster board
Step-by-step explanation:
2Conditions:
-greatest number of 1 item
-still receive change
If you go for the cheapest items like pencil or eraser you will pay with $10 for
$0.10* 100items= $10 yet no change
If you go for second most cheapest pen $0.25 you can by
if you buy 4 pencils and each with $0.25 you will pay $1
for $ 10 you can get 4*10 = 40 pencils yet no change
if you go for the third cheapest item is the poster board
$ 1.50*2= $3 so $1.50*6 =$9 and the change will be $10-9$ = $1

In 2008, the price of gasoline was $2.79 per gallon. In 2009, the price of gasoline was
$3.79 per gallon. What is the percent of increased in the price of gasoline, rounded to
the nearest whole percent? Type in your number with NO decimals and a % after the number.
Answers
Answer:
36%
Step-by-step explanation:
line up $ and % data like this:
$2.79 represents 100%
$3.79 represents X%
cross multiply
X*2.79 = 3.79*100
divide both sides by 2.79
X= 3.79*100 / 2.79 ≈ 136%
so it increased 36%
The sum of two positive numbers is 37, and their difference is 7. If x and y represent the unknown numbers, which two
equations belong to the system of equations that represents this situation?
Answers
Answer:
C & D. check the image just in case the order changes
Step-by-step explanation:
A system of equations is x + y =37 and x - y = 7 the positive numbers are 22 and 15.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
The sum of the two positive numbers is 37, and their difference is 7.
Let x and y be the numbers:
x > 0 and y > 0
x + y =37
x - y = 7
The above two equations represent the situation where the sum of two positive numbers is 37, and their difference is 7.
After solving the above equation by elimination method:
2x = 44
x = 22
22 - y = 7
y = 22 - 7
y = 15
Thus, a system of equations is x + y =37 and x - y = 7 the positive numbers are 22 and 15.

Calculating income with Commission
A salesperson earns $600 per month plus a commission of 20% of sales. Find the minimum amount of sales need to receive a total income of at least $1500 per month.
Answers
Answer:
$4500Step-by-step explanation:
Step one:
given data
monthly earning= $600
commission =20%= 0.2
let the number of sales be x
and the total earnings be y
Hence the expression for the earnings is given as
y=0.2x+600
Step two:
Required:
the value of x. when y=$1500
1500=0.2x+600
1500-600=0.2x
900=0.2x
divide both sides by 0.2
x=900/0.2
x=4500
The minimum amount of sales need is $4500

So you will have to substitute the coordinates into the equation. Let (x1,y1) be (-3,4) and (x2,y2) be (5,-4) :

$9000 was borrowed from two sources, one that charges 20% simple interest and the other that charges 5% simple interest. If the total interest at the end of 1 year was $1500, how much money was borrowed from each source?
Answers
Answer:
The amount borrowed at 20% simple interest was $7,000, while the amount borrowed at 5% simple interest was $2,000.
Step-by-step explanation:
Let x represents the amount borrowed at 20% simple interest.
Let y represents the amount borrowed at 5% simple interest.
Therefore, the amount borrowed at 5% simple interest will be:
y = 9000 - x ........................... (1)
As a result, we will have:
20%x = interest at the end of 1 year from the amount borrowed at 20% simple interest
5% * (9000 - x) = 450 - 5%x = interest at the end of 1 year from the amount borrowed at 5% simple interest
Since the total interest at the end of 1 year was $1500, we have:
20%x + 450 - 5%x = 1500
We can now solve for x as follows:
20%x - 5%x = 1500 - 450
15%x = 1050
x = 1050 / 15%
x = 7000
Substituting x = 7000 into equation (1), we have:
y = 9000 - 7000
y = 2000
Therefore, the amount borrowed at 20% simple interest was $7,000, while the amount borrowed at 5% simple interest was $2,000.

2. A shop owner raises the price of a $100 pair of shoes by 50%. After a few weeks,
because of falling sales, the owner reduces the price of the shoes by 50%. A
customer then says that the shoes are back at the original price.
a. What is the mistaken assumption here?
b. Why is that assumption incorrect?
c. What do the shoes actually cost now?
d. By what percent should the shoes be decreased in order to have the price
back at $100?
Kk
Answers
Answer:
the customer is wrong
Step-by-step explanation:
when he raised then 50 % they became $150 and then If you do the work 50% of $150 is $75 .
100+%50
150
150-%50
75
The customer is wrong because the new price of the shoe is $75 and not $100.
When the shop owner raises the price of a $100 pair of shoes by 50%, then the new price will be:
= $100 + (50% × $100)
= $100 + $50
= $150
Then, the owner reduces the price by 50%, then the new price will be:
= $150 - (50% × $150)
= $150 - $75
= $75
Therefore, the new price is $75.

C.the average amount spent out of the udget each month
D.the predicted amount of time after which the entire budget will. e spent
Answers
Answer:
A. the total amount of the budget given to the country
Step-by-step explanation:
In order to know the answer, you have to check what the y-axis represents. In the graph above, it represents the "Budget Remaining," which is expressed in thousands of dollars. On the other hand, the x-axis represents the "Time," which is expressed in months.
Point (0,18) shows the total amount of the budget for the Cultural Events in the country. It starts at 18,000 dollars and decreases as months pass by. This is shown by the graph's "negative slope." This means that as the number of months increases, the amount of money decreases.
