Answer:
First answer
Step-by-step explanation:
7 is the registration fee: it's always the same, they only pay it once. The 5 dollars is multiplied by the amount of weeks in camp.
Two weeks, for example, will be 5 dollars × 2 weeks + 7 dollars = 17 dollars.
All the money paid = the registration fee and the weekly costs together = 127 dollars.
