Question

Roberto decided to buy a new pair of running shoes for the season because last years' were alreadygiving him blisters. He purchased the running shoes for $220. He runs at least 5 times a week. After 12weeks, what is the cost of wear for the running shoes?

Answer 1

First let's find the number of times Roberto worn the shoes.

If he uses 5 times a week and we want after 12 weeks, the total number of uses is:

`5\cdot12=60`

Now, to find the cost of wear, we just need to divide the price by the number of times the shoes were worn. So we have:

`(220)/(60)=(22)/(6)=(11)/(3)=3.67`

So the cost of wear is $3.67.
