Answer:
x= (y+2)/5
Step-by-step explanation:
Let f(x) = y
y = 5x -2
Adding 2 on both sides
y +2= 5x
Divinding by 5 in both sides
(y+2)/5 = x = f*(x)
Therefore,
f*() = (y+2)/5

Answer:
A. 10%
Step-by-step explanation:
percent change = (new number - old number)/(old number) * 100%
The new number is the increased wage, $8.25, and the old number is the original wage, $7.50.
percent change = ($8.25 - $7.50)/($7.50) * 100%
percent change = ($0.75)/($7.50) * 100%
percent change = 0.1 * 100%
percent change = 10%
Since the percent change is a positive number, it is a percent increase.
The percent increase was 10%.
Answer: A. 10%
