Joshua is changing his cell phone service. one data package that he is interested in charges a set-up fee of $28 and $8 per month. the other data package has no set-up fee but charges $12 per month for the same plan. after how many months will both packages cost the same?

After 7 months will both packages cost the same.

Step-by-step explanation:

Let the month after which both the packages will cost the same be x.

Cost of data package-1 for x months = $28+$8x

Cost of data package-2 for x months =$12x

Cost of data package-1 for x months = Cost of data package-2 for x months

After 7 months will both packages cost the same.
