Mona wants to buy carpet for a floor in her house. The floor is rectangular with a width of 5 m and a length of 8 m. Two shops s

Answer:

Mona will save a total of $7 by going to Carpet World.

Step-by-step explanation:

First, we need to calculate the total area of the floor by multiplying the width by the length...

5m * 8m = 40m

Now we calculate the amount that it would cost to buy the carpet from each of the establishments. For the first establishment, we can buy 16 $m^{2}$ and get the next 8 $m^{2}$ half off and that would leave another 16 $m^{2}$ at full price. The second establishment we have a 5% off (0.95 of official price) for every 8 $m^{2}$ , since out total area is 5 times this amount then our total will have a 5% off.

Establishment 1: (16 $m^{2}$ * 2.20) + (8 $m^{2}$ * 1.10) + (16 $m^{2}$ * 2.20) = $79.20

Establishment 2: (40 $m^{2}$ * 1.90) * 0.95 = $72.20

Difference: 79.20 - 72.20 = $7

Mona will save a total of $7 by going to Carpet World.
