Question

Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $9 monthly fee and charges an additional $0.13 for each minute of calls. The second plan has a $16 monthly fee and charges an additional $0.09 for each minute of calls. For how many minutes of calls will the costs of the two plans be equal

Answer 1

the number of minutes of call when the two cost plans would be equivalent to each other is 175 minutes

Explanation:

The computation of the number of minutes of call when the two cost plans would be equivalent to each other is shown below:

Let us assume the number of minutes be x

Now the equation is

$9 + 0.13x = $16 + $0.09x

0.13x - 0.09x = $16 - $9

0.04x = $7

x = $7 ÷ 0.04

= 175 minutes

Hence, the number of minutes of call when the two cost plans would be equivalent to each other is 175 minutes
