Answer:
Cost to paint 4 walls of a room = $24.20
Cost of painting 3 walls of a room =$18.15
Step-by-step explanation:
(a) Abby purchased 4 2/5 gallons of paint to paint 4 walls of a room in her house.
![4\frac{2}{5}gallons \ of \ paint = \frac{4*5+2}{5} =\frac{22}{5}](https://tex.z-dn.net/?f=4%5Cfrac%7B2%7D%7B5%7Dgallons%20%5C%20of%20%5C%20paint%20%3D%20%5Cfrac%7B4%2A5%2B2%7D%7B5%7D%20%3D%5Cfrac%7B22%7D%7B5%7D)
1 gallon cost = 5.50
So 22/5 gallons cost = ![\frac{22}{5} * 5.5= 24.20](https://tex.z-dn.net/?f=%5Cfrac%7B22%7D%7B5%7D%20%2A%205.5%3D%2024.20)
Cost to paint 4 walls of a room = $24.20
(b)cost of painting 4 walls of a room = $24.20
cost of painting 1 wall of a room = ![\frac{24.20}{4} =6.05](https://tex.z-dn.net/?f=%5Cfrac%7B24.20%7D%7B4%7D%20%3D6.05)
Cost of painting 3 walls of a room = 6.05 * 3= $18.15
