Answer:
$47.25
Step-by-step explanation:
Earnings = (rate of pay)(number of hours worked)
Here,
Earnings last weekend = ($8.75/hr)(5.4 hrs) = $47.25
Set up the conversion factor like this:

The inches are in the denominator while the feet are in the numerator in the conversion factor. It's set up this way because the numerators and denominators have to be able to cancel out. In this case, the inches would cancel out, and you would end up with 3/12 feet, which is also 0.25 feet. The turtle walks 0.25 feet per second.
12-5=7
21-12=9
x-21=11
21+11=32
x=32
