To answer this first we need to find out how much Tiffany earns per hour and then we will multiply. lets do it:-
77.28 ÷ 4 = 19.32
$19.32 per hr
CHECK OUR WORK:-
19.32 × 4 = 77.28
we were RIGHT!!
Now lets see how much she earns in 15 hrs.
19.32 × 15 = 289.8
Tiffany earns $289.8 to work for 15 hrs.
CHECK OUR WORK:-
289.8 ÷ 15 = 19.32
we were RIGHT!!
So, Tiffany earns $289.8 to work for 15 hrs.
