Given,
Garcia’s students were asked to find 220% of 75, we need to find who did incorrect answer among Amy, Braden, Colton and Danielle
Amy multiplied 2.20 by 75 to find my answer.”
220/100×75=2.2
His answer is correct
Barden
Braden created table for 100, 100 and 20% and added. This will be equivalent to finding 220%
Braden is correct.
Colton created table for 100%, 10% and 10% percent and added these.
But this addition would result in 100+10+10 =120% not 220%
Hence Colton is wrong.
Danielle divided 75 by 5 to find 20%.
Then he added 75 twice to find his answer.
Danielle is correct.
Hence Colton got the wrong answer

Mr. Jamison will stain the deck in his backyard, the deck has an area of 752.4 sqaure feet. If the deck is 33 feet long how wide is it? Justify your procedure.
Answers
answer:The width of the deck is 22.8 feet.
Step-by-step explanation:
Since we have given that
Area of the deck = 752.4 square feet
Length of deck = 33 feet
Let width of deck be 'x'.
Since Deck is in the shape of rectangle.
As we know the formula for "Area of rectangle ":
\begin{gathered}Area=Length\times width\\\\752.4=33\times x\\\\\dfrac{752.4}{33}=x\\\\22.8=x\end{gathered}
Area=Length×width
752.4=33×x
33
752.4
=x
22.8=x
Hence, the width of the deck is 22.8 feet.

A school allots £1500 to spend on a trip to the theatre.
Theatre tickets have a regular cost of £25 each and are on offer for 1/5 off.
A train ticket for the day will cost £15 each.
If 2 teachers and the maximum number of students attend, how many students go on the trip?
Answers
Answer:
40 students
Step-by-step explanation:
If the tickets are 1/5 that means they cost 4/5
25 * 4/5 = 20
The tickets cost 20 and the train costs 15 so the total per person is 35
Teachers: 2 at 35 = 70
1500 -70 = 1430
Take 1430 / 35 =40.85714286
We can send 40 students
Answer:
40
Step-by-step explanation:
since the school allots £1500 to spend on a trip to the theatre. Theatre tickets have a regular cost of £35 each and are on offer for 1/5 off
therefore 4/5*35 = 28 for the tickets
:
A train ticket for the day will cost £15 each.
therefore total cost for each: 28 + 15 = 43 pounds each
:
If 2 teachers and the maximum number of students attend, how much money will the school have left over?
:
let s = no. of students
43(s+2) =< 1500
43s + 86 =< 1500
43s =< 1500 - 86
43s =< 1414
s =< 1414/43
s =< 32.88, 32 students max
:
find how much left over. plus 2 teachers = 34 people
1500 - 43(34) =
1500 - 1462 = 38 pounds left over

The profit y(in dollars) for a business from selling x coats is represented by y=47x . Graph the equation.
Answers
HOPE IT HELPS
The graph of the equation is attached .
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
The slope-intercept form of the line equation
y= mx + c
where m is the slope
b is the y-intercept
We are Given that the profit y (in dollars) for a business from selling x coats is represented by the equation
y=47x .
Now comparing with the slope-intercept form of the line equation;
m = 47
We know that the value of the y-intercept can be determined by setting x = 0
substitute x = 0 in the equation
y = 47(0)
y = 0
Thus, the y-intercept b = 1
Thus,
The slope m = 47
The y-intercept b = 1
The graph of the equation is also attached.
(1,47) (2,94) (3,141)
Hence, the line passes through the origin with the y-intercept 0.
