Given: Two rents plans and the costs
To Determine: The miles traveled when the two plans cost the same and the cost when the two plans cost the same
Solution: Let the total miles covered for each plan be
The cost of the first plan would be
The cost of the second plan would be
If the two cost is the same, then
Solve for x by collecting like terms
The cost when the two plans cost the same would be
Hence, the miles covered when the plans cost the same is 80 miles
The cost when the two plans cost the same is $64
