Determine the store with the best price per unit

It should be noted that the store with the best has the least price per unit.

So, we have:

Store 1

Convert quantity to feet

The unit rate is:

Rate = $0.308 per feet

Store 3

The unit rate is:

Rate = $0.283 per feet

Store 4

Convert quantity to feet

The unit rate is:

Rate = $0.267 per feet

From the calculations above; store 1 has the least unit rate.

Hence, store 1 has the best price per unit
