Answer: 5 hours
Step-by-step explanation: Since every hour is 5 dollars, and Tony babysat for 6 hours, basically do 6 x 5, which'll give you 30 ($)
Soo, since we have 30$, how many more hours do we need to get $55? (Don't forget: an hour is 5 dollars)
Anyways, we can pretty much do this: 55 - 30, which equals 25
Now, All we need to do is figure how many hours will give us $25? Wellllll, we would need 5 more hours. 5 x 5 = 25

I KNOW I DID IT A DIFFEREMT WAY, BECAUSE I LOOKED AT THE PROBLEM FIRST AND DIDN'T SEE THE ANSWER CHOICES YET. Anyways, the first answer choice is correct.
