Let x be equal to the number of minutes

Then we have the following equation:

(0.03)x + 29.95 = 38.95

(0.03)x = 9.00

x = 300

Answer: x = 300 minutes for the month of october

You can check to see if this is correct by substituting x = 300 back into the original equation:

(0.03)x + 29.95 = 38.95

(0.03)(300) + 29.95 = 38.95

9 + 29.95 = 38.95

38.95 = 38.95 :)

let m = number of minutes.

29.95 + .03m = 38.95

.03m = 9

m = 300

300 minutes

Let's assume that, in October, Parkers spent  x  minutes, then

0.03x + 29.95 = 38.95

0.03x = 38.95 – 29.95

0.03x = 9

x = 9 ÷ 0.03

x = 300 (minutes)
