Answer 1

To find out how many months Mira's cell phone bill covers, we first need to account for the activation fee and then determine how much of the bill is left for the monthly service.

1. Identify the total bill: $412
2. Subtract the activation fee: $100
3. Determine the remaining amount for the monthly charges: $412 - $100 = $312
4. Find the monthly cost: $52
5. Divide the remaining amount by the monthly cost to find the number of months: $312 ÷ $52

The operations needed to solve this problem are subtraction to subtract the activation fee from the total bill and division to calculate how many months the bill covers.

Therefore, the correct response is subtraction and division.
