Answer 1

To find:

At which store Zachary will get the lowest price on 4 tires

Step-by-step explanation:

[ Check the attached picture for the table. ]

Store R.

Given, price of 1 tire is $150.

Then the price of 3 tires is $(3 × 150) = $450.

This is also the price of 4 tires since the 4th tire comes for freè, as given.

Store S.

Given, price of 1 tire is $200.

On buying 4 tires, one gets $70 off on each tire.

So cost of 1 tire is $(200 - 70) = $130.

Thus the price of 4 tires is $(4 × 130) = $520.

Store T.

Given, price of 1 tire is $175.

Then the price of 4 tires is $(4 × 175) = $700.

Here $200 is off the total price.

Thus the price of 4 tires is $(700 - 200) = $500.

Store V.

Given, price of 1 tire is $130.

Here the price of 4 tires is $(4 × 130) = $520.

Here 10% is off the total price.

Thus the price of 4 tires is $520 (1 - 10/100) = $468.

Conclusion:

Store R comes with the lowest price of $450 for 4 tires.
