Question

A truck can be rented from Company A for ​$ 120 a day plus ​$0.30 per mile. Company B charges ​$50 a day plus ​$0.40 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.

Answer 1

Answer:

Explanation:

t the truck is driven X miles per day

Charges of company A will be = 90+0.4X

Charges of company B will be =30+0.7X

Let us find out value of X when charges of both companies are same

which means that   90+0.4 X= 30+0.7X

                            90-30      = 0.7X-0.4X

                            60    = 0.3X

                             60/0.3 = X

                             X= 200

The charges of both companies will be same if truck is driven 200 miles per day

Company A will have better deal if truck is driven more than 200 miles per day ( because per mile rate of company A is less than company B)

Answer 2

Explanation:

company a = 120 + 0.3 × miles

company b = 50 + 0.4 × miles

120 + 0.3 m = 50 + 0.4 m

120 - 50 = 0.1 m

70 = 0.1 m

m = 700 miles
