Answer 1

(a) Locker A has the better deal

Explanation:

Given

`A = (\$28)/(yd^2)` -- monthly

`B = (\$1.43)/(ft^2)` --- weekly

`1\ month = 4\ weeks`

Required:

Determine which gives the better price

`B = (\$1.43)/(ft^2)` --- weekly

Convert to monthly rate:

`B = (\$1.43*4)/(ft^2)`

`B = (\$5.72)/(ft^2)` --- monthly

Convert ft^2 to yd^2

`1ft^2 = 0.111yd^2`

So, we have:

`B = (\$5.72)/(0.111yd^2)`

`B = (\$51.53)/(yd^2)` --- monthly

By comparing:

`A = (\$28)/(yd^2)`

`B = (\$51.53)/(yd^2)`

Locker A has the better deal
