Barbara worked there 7 hours a day for 10 days in August. How much did the hotel pay her?
Amount that the hotel paid Barbara for the first 4 hours
= 4 x 7.50
= $30
Duration that Barbara worked after the first 4 hours
= 7 - 4
= 3 h
Amount that the hotel paid Barbara for the next 3 hours
= 3 x 14
= $42
Amount that the hotel paid Barbara per day
= 30 + 42
= $72
Amount that the hotel paid Barbara for 10 days
= 10 x 72
= $720
Answer(s): $720
