Answer 1

To determine how many months Mira's cell phone bill covers, we need to first understand the total amount she paid and the individual costs associated with the phone service.

1. The total bill is $412.
2. She paid an activation fee of $100.
3. The monthly cost for the phone is $52.

To find out how many months the bill covers, we can follow these steps:

1. Subtract the activation fee from the total bill to get the total amount that is for the monthly service: \[ 412 - 100 = 312 \]

2. Now divide this amount by the monthly cost to find the number of months: \[ 312 \div 52 = 6 \]

So Mira’s bill covers 6 months.

The operations needed to solve this problem are:

• Subtraction (to find out how much of the bill was left after the activation fee)
• Division (to calculate the number of months based on the remaining amount and the monthly cost)

Thus, the correct response is: subtraction and division.
