Question

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

If we use X to represent the amount of quarts for the inside of the barn we can write an equation for this. The outside needs 19 quarts more so we can say this is (x+19)

x+x+19=107
2x+19=107
2x=88
x=44 quarts

convert to gallons by dividing by 4 and you have 11 gallons for the inside
