Answer:
profit = 129.63% (to the nearest hundredth) as a percent of the price the store paid for the book
Step-by-step explanation:
Use the percentage change formula:
percent change = [ (difference between the initial value and the final value) ÷ initial value] x 100
= [ (6.20 - 2.70) ÷ 2.70 ] x 100
= [ 3.5 ÷ 2.70 ] x 100
= 37/27 x 100
= 129.6296296...
= 129.63% (to the nearest hundredth)

Answer:
2.32 gallons of paint
Step-by-step explanation:
First, find the area of all 4 sides of the room, with the equation A = lw
11(10)
= 110 (for 2 of the walls)
18(10)
= 180 (for the other 2 walls)
Add these up:
110 + 110 + 180 + 180
= 580
Then, divide this by 250:
580/250
= 2.32
So, 2.32 gallons of paint will be needed to paint the room.
