At tire depot a pair of new tires sells for $216. The manager's special advertises the same tires selling at a rate of $380 for 4 tires. How much do you save per tire if you purchase the manager's special?

Cost of a pair of new tires at tire depot = $216

Mangers special rate for selling the same tires is $380 for 4 tires

So

The manager special cost of 4 tires is = 380 dollars

Then

Cost of a single tire under managers special scheme = 380/4 dollars

= 95 dollars

Then

The amount of savings per tire by

using managers special scheme = (216 - 95) dollars

= 121 dollars

So by using the managers special purchase scheme it is possible to save $121 per tire. I hope the procedure is clear for you to understand.

First you must fnd the unit rate of the manager's special, 380 divided by 4 = $95

Then you need to to find the unit rate for 1 tire at regular price,

216 divided by 2 = 108

Then you subtract 95 from 108

108-95=13

You save $13 per tire
