Emma worked there 9 hours a day for 18 days in September. How much did the store pay her?
Amount that the store paid Emma for the first 5 hours
= 5 x 7.80
= $39
Duration that Emma worked after the first 5 hours
= 9 - 5
= 4 h
Amount that the store paid Emma for the next 4 hours
= 4 x 15
= $60
Amount that the store paid Emma per day
= 39 + 60
= $99
Amount that the store paid Emma for 18 days
= 18 x 99
= $1782
Answer(s): $1782
