deal?
OA. 9
B. 6
O C. 5
D. 11

Answer 1

Let x be the number of hours of car sharing per year. Then the cost of using Company A is given by:

Cost of Company A = $125 + $7x

The cost of using Company B is given by:

Cost of Company B = $110 + $10x

We want to find the minimum number of hours of car sharing per year such that Company A is a better deal than Company B. In other words, we want to find the value of x such that:

Cost of Company A < Cost of Company B

125 + 7x < 110 + 10x

15 < 3x

5 < x

So the minimum number of hours of car sharing per year to make Company A a better deal is 6 hours. Therefore, the answer is B!!
