Mickey charges $15,$30,$45 and 60 for babysitting 1,2,3 and 4 hours respectively. Is the relationship between the number of hours and the amount changed proportional if so find the unit rate. if not, explain why

Yes

15 dollars / hour

Step-by-step explanation:

Yes the numbers are proportional.

Basically the formula is

y = 15*x where x stands for the number of hours babysat.

So as x goes up so does the total and it goes up by the same amount.

The unit rate is 15 dollars / hour.
