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).
