The rate of change is 4 so your answer would be D. 4
Solution: We are given that:
5 people can paint 7 walls in 21 minutes
Therefore, 1 person can paint 7 walls in 
minutes
Which means 1 person can paint 1 wall in 
minutes
Now, 3 people can paint 1 wall in 
minutes
Therefore, 3 people can paint 5 walls in 
minutes

Answer:
The area of the base is 15 in²
Step-by-step explanation:
33 3/4 = 33.75
2 1/4 = 2.25
To calculate the area base of a rectangular prism we have to use the following formula:
a = area
v = volume = 33.75 in³
h = height = 2.25 in
v = a * h
we solve a
a = v / h
we replace the values that we know
a = 33.75 in³ / 2.25 in
a = 15 in²
The area of the base is 15 in²
Suppose a square is 100%, 50%: the square is divided into two equal parts, and one of them is shaded, therefore it is 50%. 25%: the square is divided into 4 equal parts, and one of them is shaded, therefore it is 25%. 150%: there are two squares, each divided into 2 equal parts, and 3 of them is shadowed, therefore it is 150%
