# Problem of the Week Problem A Deciding About Data

The Webb family is trying to decide on a new monthly internet plan. There are three choices:

• Plan A: $$\10$$ for the first $$10$$ GB of data, and each additional $$2$$ GB costs $$\5$$.

• Plan B: $$\40$$ for the first $$20$$ GB of data, and each additional $$10$$ GB costs $$\10$$.

• Plan C: $$\80$$ for unlimited GB of data.

Note that for Plan A, additional data has to be purchased in $$2$$ GB increments. Similarly, for Plan B, additional data has to be purchased in $$10$$ GB increments.

After keeping track of data used, the family decides they will use between $$25$$ GB and $$40$$ GB of data each month. Which plan should the Webb family choose? Justify your answer.
