Use the five steps for problem sovling.
Company A charges $25 per month plus $0.22 per minute for cell phone service. Company B charges $35 per month plus $0.12 per minute. How many minutes of usage is needed in one month to make Company B a better deal?

solve:
.12m + 35 < .22m + 25
The five step-method is probably a term your teacher uses, and is not generally known.
The number of steps shouldn't really matter.
Here is the way I would do this ....
.12m + 35 < .22m + 25
-.1m < -10
m > 100
so for usage of more than 100 minutes, plan B would be better
check with a number like 150 minutes
.12m + 35 < .22m + 25
