Answer 1

Answer:

(a) Locker A has the better deal

Step-by-step explanation:

Given

$A = \frac{\ 28}{yd^2}$ -- monthly

$B = \frac{\ 1.43}{ft^2}$ --- weekly

$1\ month = 4\ weeks$

Required:

Determine which gives the better price

$B = \frac{\ 1.43}{ft^2}$ --- weekly

Convert to monthly rate:

$B = \frac{\ 1.43*4}{ft^2}$

$B = \frac{\ 5.72}{ft^2}$ --- monthly

Convert ft^2 to yd^2

$1ft^2 = 0.111yd^2$

So, we have:

$B = \frac{\ 5.72}{0.111yd^2}$

$B = \frac{\ 51.53}{yd^2}$ --- monthly

By comparing:

$A = \frac{\ 28}{yd^2}$

$B = \frac{\ 51.53}{yd^2}$

Locker A has the better deal
