Answer:
$69.50
Step-by-step explanation:
First you need to know how much wall you're going to cover.
Each wall us 12 ft by 8ft
The area of a rectangle can be computed with the formula:
A = L x W
Using the given:
A = 12ft x 8 ft
= 96 ft²
This is the area of each wall. Since all 4 walls will be covered, you multiply the area of 1 wall by 4.
96 ft² x 4 = 384 ft²
Next we subtract the area of the windows and the door because we won't be covering that.
384 ft² - 52 ft² = 332 ft²
So the total area we are covering with wall paper is 332 ft².
To get the cost of the wallpaper needed, we just need to compute first how many bolt we will need. Divide the total area to be covered by the area of one bolt of wall paper.
332 ft² ÷ 72 ft²/bolt = 4.61 bolts ≅ 5 bolts
Then we multiply it by the price per bolt:
5 bolts x $13.90/bolt = $69.50
First, find the lowest common multiple of 5 and 8 and it is 40.
So
-32/40 - 35/40
= -67/40
Answer: 680

I’m smart
It is 6 units because if you divide 9 by 3 you get 3 and you multiple that by 2 to make it 6:9 which is equal to 2:3
