Question

Volodomyr has a cell phone. He has a "pay as you go" plan that follows a linear relationship.

• Two months ago, he paid $32 for 100 minutes of phone calls.
• Last month, he paid $36 for 300 minutes of phone calls.

How much can he expect to pay this month if he used his phone for a total of 400 minutes?

Answer 1

38$

you just have to add and think about it as 30$ is the membership fee and for every 2$ you get 100 minutes
