Question

Under her cell phone plan, Nora pays a flat cost of $43 per month and $3 per gigabyte. She wants to keep her bill under $65 per month. Which inequality can be used to determine g, the maximum number of gigbytes Nora can use while staying within her budget?

Answer 1

7.3 months

Explanation:

Given data

Flat cost= $43

Cost per gigabyte= $3

Let the function for the total cost be described as

y=mg+c

where g is the number of gigabyte

We are told that she wants to keep y<$65

65<3g+43

65-43<3g

22<3g

22/3<g

g<7.3 months

Hence the number of months should be less than 7.3
