Answer 2

Answer: Crystal will earn $11.81.

Step-by-step explanation:

Since we have given that

Cost per hour mowing lawns = $5.25

Let the number of hours be 'h'.

Let the amount of money be 'm'

So, According to question, we get

$m=5.25\times h\\\\m=5.25h$

Here h = 2 hours and 15 minutes

So,

$h=2\frac{15}{60}\\\\h=2\frac{1}{4}\\\\h=\frac{9}{4}$

So, Crystal will earn if she works for 2 hours and 15 minutes will be

$m=5.25\times \frac{9}{4}\\\\m=\frac{47.25}{4}\\\\m=\ 11.81$

Hence, Crystal will earn $11.81.
