Question

chad is trying to find a new cell phone plan chalk talk offers a plan for $62.70 each plus $1.20 for each megabyte of data used. ring-jingle cells offers of a plan for $63.70 per month plus $1.25 for each megabyte of data used chad wants to know how many megabytes of data he would have to use to make the cost of the two plans the same

create a system of equation to model the situation above and use it to determine if there is a viable solution or not? tell if its viable solution or not?

Answer 1

Let x be the number of megabytes of data used.

For Chalk Talk:
Cost = 62.70 + 1.20x

For Ring-Jingle Cells:
Cost = 63.70 + 1.25x

Setting the two costs equal to each other:
62.70 + 1.20x = 63.70 + 1.25x

Solving for x:
0.05x = 1
x = 20

Therefore, Chad would have to use 20 megabytes of data to make the cost of the two plans the same. Since this is a viable solution, he can choose either plan.
