Algebra 1

your uncle buys a new car that comes with seven new tires, one for each wheel and three spare tires. He decides to be economical by using the tree spares as much as the other four tires. If he drives 22,750 miles and each tire has been used equally, what will be the wear in miles on each tire?

i think that you would divide the total miles by seven and that is your answer, 22,750 is divisible by 7, the number is 3,250. but i feel that is too easy.
well, can someone tell me if I'm doing this right?
THANKS!

  1. I think you're right as far as you went. However, if each tire went 3,250 miles, then the car would only have one tire at a time. <g>

    How about multiplying: 3,250 * 4 = 13,000 miles.

    That makes sense because if he'd started with 8 tires and changed 4 tires at the halfway point (22,750 / 2) each tire would have 11,375 miles of wear.

  2. what you have, i understand, but he bought seven, not eight, so, thank you for telling me that, except now i'm stuck.
