Question

Freddy earns $15 per hour. The store offers him a raise–a 4% increase per hour. After the raise, how much will Freddy make per hour?

Answer 1

Freddy's hourly rate after a 4% raise will be $15.60. The raise is calculated by multiplying his current hourly wage by the percentage increase and adding it to his existing wage.

Step-by-step explanation:

If Freddy currently earns $15 per hour and receives a 4% raise, we first need to calculate the amount of raise he will get per hour. The percentage change or growth rate for his pay can be computed by multiplying his current pay by the raise percentage in decimal form.

A 4% raise means that Freddy will get an additional 4/100 of his current hourly pay. To calculate this, we multiply $15 by 0.04 (4% in decimal form):

$15 × 0.04 = $0.60

So, Freddy's raise is $0.60 per hour. Now we need to add this raise to his original hourly rate to find out how much he will make after the raise:

$15 + $0.60 = $15.60

After the 4% raise, Freddy will earn $15.60 per hour.
