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.
