To determine

(a)

To Find:

A table for the cost of cell phone plans.

### Explanation of Solution

The monthly cost of plan A is $25. The plan A includes 1 GB data. Each additional 100 MB cost$2.

Then, every additional 500 MB costs $10. The monthly cost of plan B is$40.

The plan B includes 1 GB data.

Each additional 100 MB cost $1.5. Then, every additional 500 MB costs$7.5.

The monthly cost of plan C is $60. The plan C includes 1 GB data. Each additional 100 MB cost$1.

Then, every additional 500 MB costs \$5.

To determine

(b)

To Find:

A formula for monthly cost of cell phone plan.

To determine

(c)

To Find:

The charge for each plan for 2.2GB, 3.7GB, 4.9GB.

To determine

(d)

The number of gigabytes of data used.
