Question

Mary earns $7.25 an hour. She can determine her salary, s, for the number of hours she works, h, by using the equation s = 7.25h. What best describes why this is a proportional relationship?

Answer 1

see the explanation below

Explanation:

Given data

We are given that her salary is determined by the function

s= 7.25h

the relationship between h and s is a proportional relationship because

when h increases the value of s also increases and vice versa

check

for h= 2

s= 7.25(2)

s= 14.5

for h= 1.5

s= 7.25(1.5)

s= 10.875
