You are planning to purchase displays for your store which has 2400 sq ft of selling space. each display has a footprint of 10ft
polet [3.4K]
For this case, the sales space of the displays is given by:
 (2400) * (1-0.60) = 960 feet ^ 2
 We now look for the area of each display:
 (10) * (4) = 40 feet ^ 2
 With this information, we can then search the number of displays:
 N = (960) / (40)
 N = 24 displays
 Answer:
 
you can fit 24 displays.

Paladinen [302]
Solve:-

Find unit price per pack.  

6-Pack:-

2.49 ÷ 6 = <span>0.41
$</span><span>0.41 per can

12-pack:-

3.99 </span>÷ 12 = 0.33
<span>0.33 per can

24-pack:-

5.49 </span>÷ 25 = <span>0.22
</span><span>0.22 per can
</span>
The cheapest is 24-pack, because the unit price for that is the cheapest. After that pack is the 12-pack one because that is cheaper than the 6-pack. and last is the 6-pack. <span />
