I think that this is right, but I assumed that the ceiling has the same dimensions as the wall you would need 4 gallons for 2 coats.
Work:
20x8= 160 (square feet for 1 wall)
160x5=800 (i assumed there are 4 walls and 1 ceiling)
800x2=1600 (you need 2 coats)
1600/400=4 (each gallon includes 400 square feet)

Nat2105 [25]

After 2 hours time ,  both Abe and Gabe to cost the same amount .

<u>Step-by-step explanation:</u>

Here we have , a car needs fixing and Abe can fix it for $70 per hour with a $60 part, but Gabe can fix it for $80 an hour with a $40 part. We need to find How long will it take for both Abe and Gabe to cost the same amount .Let's find out:

Let the time for which both Abe and Gabe to cost the same amount be x hours, so according to question scenario we will have equation as :

⇒ 70x+60=80x+40

⇒ (70x+60)-70x=(80x+40)-70x

⇒ 60=(10x+40)

⇒ 60-40=(10x+40)-40

⇒ 20=10x

⇒ x=2

Therefore , After 2 hours time ,  both Abe and Gabe to cost the same amount .
