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.  

Well lets find the value of our dividend base!
So we have 30 as the divisor~
We know the dividend is a 3 digit number which is obviously the least.
And we know about the remainder of 8.
We have to find the least number that can be divided with 30 so keep multiplying 30 until you find your least number.
30 * 1 = 30
30 * 2 = 60
30 * 3 = 90
30 * 4 = 120
So now we have 120 which is the least 3 digit number that can be divided by 30.
All we have to do now is add 8 as the remainder and we should be good!
120 + 8 = 128
Our remainder is left to be 8!
