Question

2. Jay needs 19 quarts more paint for the outside of his barn than for the inside. If he uses 107 quarts in all,

how many gallons of paint will be used to paint the inside of the barn?

Answer 1

44 quarts to paint the inside

Explanation:

He needs x quarts for the inside painting and x + 19 quarts for the outside.

These two measures add up to 2x + 19, which equals 107 (quarts) total.

Then 2x = 88 quarts, and:

x = 44 quarts. This is the number of quarts needed to paint the inside; the outside requires 19 quarts more, or 63 quarts.

Note that 44 and 63 add up to 107 (quarts), as they must.
