Question

Suppose that you are trying to determine which cell phone data plan is best for you. Plan A has a flat rate of $35 per month plus $11 for each gigabyte of data you use. Plan B has a flat rate of $22 per month plus $14 for each gigabyte of data you use. Write a separate function for each data plan that describes the total cost per month when using 𝑥 gigabytes of data.

Answer 1

Plan A: C =35 +11G

Plan B: C= 22 +14G

they cost the same when 35+11G=22+14G, 3G=13, G=4 1/3, C =$82.67

Plan A is cheaper for when G>4 1/3

Plan B is cheaper when G<4 1/3
