Question

A cell phone plan costs ​$27.80 per month for 500 minutes of talk time. It costs an additional ​$0.08 per minute for each minute over 500 minutes. To get​ e-mail access, it costs 10​% of the price for 500 minutes of talk time. Your​ bill, which includes​ e-mail, is the same each month for 6 months. The total cost for all 6 months is ​$216.60. Write and solve an equation to find the number of minutes of talk time you use each month.

Answer 1

the answer is 569 minutes of cell phone talk time.

Explanation:

10% of $27.80 is $2.78

$216.60/6 months=$36.1 per month for all services.

Then, $36.1-$2.78=$33.32

$33.32-$27.80=$5.52

$5.52/$0.08=69 minutes of extra talk time.

So the answer is 569 minutes of talk time. i hope i could help:)
