Answer 1

Analyze each plan according to the given specifications.

Plan A:

The basic fee must be added to the product of 0.13 and the average messages sent.

`29.95+190\cdot0.13=54.65`

Plan B:

It already includes the cost for unlimited messages.

`53.00`

Plan C:

The plan costs the product of 0.28 and the average messages sent.

`190\cdot0.28=53.2`

When comparing these plans, the cheapest one is Plan B, which only costs $53.00.
