Answer:
(a) Locker A has the better deal
Step-by-step explanation:
Given
[tex]A = \frac{\$28}{yd^2}[/tex] -- monthly
[tex]B = \frac{\$1.43}{ft^2}[/tex] --- weekly
[tex]1\ month = 4\ weeks[/tex]
Required:
Determine which gives the better price
[tex]B = \frac{\$1.43}{ft^2}[/tex] --- weekly
Convert to monthly rate:
[tex]B = \frac{\$1.43*4}{ft^2}[/tex]
[tex]B = \frac{\$5.72}{ft^2}[/tex] --- monthly
Convert ft^2 to yd^2
[tex]1ft^2 = 0.111yd^2[/tex]
So, we have:
[tex]B = \frac{\$5.72}{0.111yd^2}[/tex]
[tex]B = \frac{\$51.53}{yd^2}[/tex] --- monthly
By comparing:
[tex]A = \frac{\$28}{yd^2}[/tex]
[tex]B = \frac{\$51.53}{yd^2}[/tex]
Locker A has the better deal
