(0.10)(0.5) + 0.35g = 0.15(g + 0.5) eli wants to combine 0.5 gallon of a 10% acid solution with some 35% acid solution to make a 15% acid solution. how much of the 35% acid solution should eli add? gallons

0.125=g

step-by-step explanation:

well you start off with the equation

(0.10)(0.5) + 0.35g = 0.15(g + 0.5)

go on to multiply everything that is set up to be multiplied (shown with parenthesis)

0.05 + 0.35g = 0.15g +   0.075

then you'll have to subtract 0.15g from both sides and 0.05 from both sides.

0.2g = 0.025

divide both sides by 0.2

and you get

g = 0.125
