Please help!!!! i suck at word problems.



Answer :

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.

Answer:

300 minutes

Step-by-step explanation:

Equation: 20 + 0.15x = 35 + 0.10x

0.05x = 15

x = 300 minutes
