Subsequent hours |

Mary worked there 9 hours a day for 15 days in August. How much did the restaurant pay her?
Amount that the restaurant paid Mary for the first 5 hours
= 5 x 11.20
= $56
Duration that Mary worked after the first 5 hours
= 9 - 5
= 4 h
Amount that the restaurant paid Mary for the next 4 hours
= 4 x 15
= $60
Amount that the restaurant paid Mary per day
= 56 + 60
= $116
Amount that the restaurant paid Mary for 15 days
= 15 x 116
= $1740
Answer(s): $1740
