.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
