A phone company charges you a monthly flat fee of $12 and $0.25 a minute per call. The bill for the month of September is $21. How many minutes were charged on this bill? a. Write an equation that models this situation using to represent the number of minutes b. Solve for and answer the question.

36 minutes

Step-by-step explanation:

Flat fee = $12

Charges per minutes = $0.25

Total charges = $21

Total charges = flat fee + charges per minutes

21 = 12 + 0.25x

21 = 12 + 0.25x

21 - 12 = 0.25x

9 = 0.25x

x = 9 / 0.25

= 36

x = 36 minutes

No

Step-by-step explanation:

0 is not the solution because 0+2=2 and 2x4 does not equal 10, it equals 8.
