Which equation can you use to determine how many gallons of the 35% acid solution should eli add

Let x = number of gallons of the 35% acid solution Eli

should add. The equation would be

0.5 gal (0.1) + x gal (0.35) = (0.5 + x)(0.15)

This would be the equation to find the answer.

Solving for x,

X = 0.125 gallons
