9. The painter bought 8 cans of paint for $12.99 each. How much did he spend on paint?

So I think we have to first figure out how many gallons is each coat of paint.

Bigger room: 3 coats paint.

Smaller room: 2 coats paint.

Total here is 5 coats of paint, and it's for 8 gallons, so each coat is 1.6 gallons (8/5).

So 1 coat of paint = 1.6 gallons.

Now, if he doesn't paint the smaller room, which takes 2 coats paint, which is 3.2 gallons, he will have 4.8 gallons left (8 - 3.2).

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

positive
