Question

An onsite oil change service charges a flat rate of $40.00 per service call and an additional $2.25 per mile fee for travel outside a certain radius. Josh budgets $200 per year for oil changes on his vehicle. He lives 7 miles outside the radius. What is the greatest number of oil changes (c) that he can schedule and keep on budget for the year? A) 3 B) 4 C) 5 D) 6

Answer 1

The answer is 3.

55.75c ≤ 200

c ≤ 3.59

Answer 2

The correct answer is option B,

Total four service can be taken.

Explanation:

Distance traveled by Josh outside the radius
`7 miles\\`

The cost of travelling
`7 miles\\` outside the radius

`= 7 * 2.25\\= 15.75\\`

The amount remaining after paying for the outside travelling

`= 200 - 15. 75\\= 184.25\\`

Number of oil service than can be taken out of the remaining amount

`= (184.25)/(40) \\= 4.60\\`

Thus total four service can be taken
