Question

You are planning a camping trip. The campsite you want to rent charges a $15 fee to reserve the site, plus an extra $3 per day, how much would it cost to camp for a week? If you had $40 to spend, how long could you stay?


It would cost $35 to camp for one week. I could camp for 6 days with $40 dollars.


It would cost $33 to camp for one week. I could camp for 7 days with $40 dollars.


It would cost $36 to camp for one week. I could camp for 8 days with $40 dollars.


It would cost $36 to camp for one week. I could camp for 9 days with $40 dollars.

Answer 1

Cost for 7 days = 15 + 3×7 = 15 + 21 = $36.

With $40: 15 + 3d ≤ 40 → 3d ≤ 25 → d ≤ 25/3 ≈ 8.33, so you can stay 8 whole days.

So the correct choice is: "It would cost $36 to camp for one week. I could camp for 8 days with $40 dollars."
