Write the equation: The phone company has a plan that costs $19.99 a month and charges $0.03 per minute. How many minutes did you talk on the phone if your bill was $107.95?

The number of minutes talk is 3,598.33 minutes

Step-by-step explanation:

The computation of the number of minutes talk is as follows:

Given that

Cost per month = $19.99 = x

Charges per minute = $0.03 = y

Bill amount = $107.95 = a

Now based on the above information

The number of minutes is

= a ÷ y

= $107.95 ÷ $0.03

= 3,598.33 minutes

Hence, the number of minutes talk is 3,598.33 minutes

so, converting firstly the mixed fractions to improper fractions and then "adding".
