Question

Donna makes $9.75 per hour at her job. Kaylee makes $4 per hour at her job, and she receives a $0.25 raise each month.

Answer 1

The number of months it will take for Kaylee to make as much as Donna is 23 months

Explanation:

Here we have amount Donna makes = $9.75/hour

Amount Kaylee makes = $4/hour with $0.25 monthly raise

Therefore, number of months, Y before Kaylee makes as much s Donna is given by the following expression;

4 + Y × 0.25 = 9.75

0.25·Y = 9.75 - 4 = 5.75

`Therefore, \ Y = (5.75)/(0.25) =23 \ months`

That means in 23 months, Kaylee will make as much as Donna per hour.
