Answer:
The number of months it will take for Kaylee to make as much as Donna is 23 months
Step-by-step 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
That means in 23 months, Kaylee will make as much as Donna per hour.
