Answer:

300 minutes

Explanation:

Equation: 20 + 0.15x = 35 + 0.10x

0.05x = 15

x = 300 minutes

So for the first one... Let's just use x for months and m for minutes.

(20m)+(.15m)

20 times the number of months plus .15 times the number of minutes

Same for the next one

(35x)+ (.10m)

35 times the number of months +.10 times the minutes.
