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}

1 gallon cost = 5.50

So 22/5 gallons cost = \frac{22}{5} * 5.5= 24.20

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

Cost of painting 3 walls of a room = 6.05 * 3= $18.15

Find the area and perimeter.
DanielleElmas [232]

Step-by-step explanation:

Perimeter = 12 + x + 6 + 2x + 5

Perimeter = 3x + 23.

Area = ½ × b × h

Area = ½ × 12 × (x + 6)

Area = 6(x + 6)

Area = 6x + 36
