Rate |
First 4 hours |
$10.50 per hour |
Subsequent hours |
$14 per hour |
Sarah worked there 9 hours a day for 15 days in March. How much did the boutique pay her?
Amount that the boutique paid Sarah for the first 4 hours
= 4 x 10.50
= $42
Duration that Sarah worked after the first 4 hours
= 9 - 4
= 5 h
Amount that the boutique paid Sarah for the next 5 hours
= 5 x 14
= $70
Amount that the boutique paid Sarah per day
= 42 + 70
= $112
Amount that the boutique paid Sarah for 15 days
= 15 x 112
= $1680
Answer(s): $1680
