Store 1

Explanation:

Given

Required

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

`Quantity = 10\ ft`

`Price = \$2.50`

The unit rate is:

`Rate = (Price)/(Quantity)`

`Rate = (\$2.50)/(10\ ft)`

Rate = $0.250 per feet

Store 2

`Quantity = 2\ yd`

`Price = \$1.85`

Convert quantity to feet

`Quantity = 2 * 3ft = 6ft`

The unit rate is:

`Rate = (Price)/(Quantity)`

`Rate = (\$1.85)/(6\ ft)`

Rate = $0.308 per feet

Store 3

`Quantity = 12\ ft`

`Price = \$3.40`

The unit rate is:

`Rate = (Price)/(Quantity)`

`Rate = (\$3.40)/(12\ ft)`

Rate = $0.283 per feet

Store 4

`Quantity = 5\ yd`

`Price = \$4.00`

Convert quantity to feet

`Quantity = 5 * 3ft = 15ft`

The unit rate is:

`Rate = (Price)/(Quantity)`

`Rate = (\$4.00)/(15\ ft)`

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
