Finally, use decimal numbers to write an expression that represents the net change in Rylee’s bank account balance for her entire shopping trip. Use your answers from parts A through C to guide you.


PART C; The original price of Rylee’s groceries was $23.50. This money is leaving her bank account, so represent the amount with a negative sign:
-$23.50.

Rylee got a 20% discount on her purchase. In other words, she got 20% of her money back. The expression that represents the net change in her bank account is
-$23.50 – (-$23.50 × 0.2).

Further simplify the expression by factoring -$23.50 from both terms:

-$23.50 – (-$23.50 × 0.2)
=
-$23.50(1 – 0.2)
=
-$23.50(0.8).

Answers

Answer:

look at explanation

Step-by-step explanation:

PART C; The original price of Rylee’s groceries was $23.50. This money is leaving her bank account, so represent the amount with a negative sign:

-$23.50.

Rylee got a 20% discount on her purchase. In other words, she got 20% of her money back. The expression that represents the net change in her bank account is

-$23.50 – (-$23.50 × 0.2).

Further simplify the expression by factoring -$23.50 from both terms:

-$23.50 – (-$23.50 × 0.2)

=

-$23.50(1 – 0.2)

=

-$23.50(0.8).

The net change to her banking account balance is $83.22.

What is net change?

The net change theorem states that when a quantity changes, the final value equals the initial value plus the integral of the rate of change. Net change can be a positive number, a negative number, or zero.

Given that, She spent $36.50 plus 8% tax.  (to calculate the tax amount, we have to multiply the cost by the percentage in decimal form)

36.50 x (8/100) =$2.92 (value of tax)

Adding to the original cost

36.50+2.92 = $39.42

Then, she spent $25 to refuel her car at the gas station.

39.42 +25 = $64.42

She bought groceries worth $23.50. At the grocery checkout, she handed over a coupon for a 20% discount on her purchase

23.50 x (20/100) = 4.7 (amount of discount)

Subtracting to the purchase

23.50 -4.7= $18.8

Hence, adding to the total cost.

64.42 +18.8 = $83.22

20 points each!!! Heather has 2 less than 5 times the amount of shoes that Donna has, Gina has 1 more than 2 times
amount of shoes that Donna has. Let x represents how many shoe Donna has.

a. Write an expression that represents how many more pairs of shoes Heather has than Gina.

b. Simplify the expression:

c. How many more pairs of shoes does Heather have is Donna has 14 pairs of shoes?

Answers

Answer:

A. (5x - 2) - (2x +1)

B.  x -1

C. 68

Step-by-step explanation:

Heather = 5 times Donna -2   H = 5D - 2

Gina = 2 times  Donna + 1    G = 2D + 1

Plug in D for X and you get

H = 5x -2

G = 2x + 1

If Heather's expression is 5x -2 and Gina's expression is 2x + 1 then to show how many more Heather has than Gina. You have to subtract Gina from Heather.

(5x - 2) - (2x +1)

Now to simplify it, you just combine all the like terms.

5x - 2 - 2x -1 = 3x - 3   and then you can simply this further by dividing all terms by 3.    x - 1

To solve how many Heather has if Donna has 14. You substitute 14 for x in Heather's equation.    5 (14) -2  =  70 - 2 = 68
