The cell phone plan from Company C costs $10 per month, plus $15 per gigabyte for data used. The plan from Company D costs $80 per month, with unlimited data.

Rule C gives the monthly cost, in dollars, of using g gigabytes of data on Company C's plan. Rule D gives the monthly cost, in dollars, of using g gigabytes of data on Company D's plan.

Which is less, C(4) or D(4)? What does this mean for the two phone plans?

The solution: is C(g) = 10 + 15g, C'(g) = 80.

Monthly pricing for utilizing 2 Gigabytes of data at Company C.

Detailed explanation:

Company C's cell phone plan is $10 per month + $15 for every gigabyte of data utilized. Company D's monthly fee is $80 and includes unlimited data.

The monthly cost for using g gigabytes of data at Company C is now: C(g) = 10 + 15g.... (1)

Again, the monthly cost for using g gigabytes of data at Company D will be as follows: C'(g) = 80......... (2) (2)

Statement C(2) = 10 + 15 2 = 40 represents Company C's monthly charges for utilizing 2 Gigabytes of data use, according to equation (1).

Thanks for your question. I had an interesting time solving this.
