Kimberly worked there 9 hours a day for 20 days in December. How much did the store pay her?
Amount that the store paid Kimberly for the first 4 hours
= 4 x 8.50
= $34
Duration that Kimberly worked after the first 4 hours
= 9 - 4
= 5 h
Amount that the store paid Kimberly for the next 5 hours
= 5 x 15
= $75
Amount that the store paid Kimberly per day
= 34 + 75
= $109
Amount that the store paid Kimberly for 20 days
= 20 x 109
= $2180
Answer(s): $2180
