Eli wants to combine 0.5 gallon of a 10% acid solution with some 35% acid solution to make a 15% acid solution. which equation can you use to determine how many gallons of the 35% acid solution eli should add?

Equation is

0.125 gallons of the 35% acid solution Eli should add.

Step-by-step explanation:

Given : Eli wants to combine 0.5 gallon of a 10% acid solution with some 35% acid solution to make a 15% acid solution.

To find : Equation can you use to determine how many gallons of the 35% acid solution Eli should add?

Solution :

Let x be the gallons of the 35% acid solution.

According to question,

For 0.5 gallon of a 10% acid solution =

For x gallon of a 35% acid solution =

For (0.5+x) gallon of a 15% acid solution =

The equation form is

Solving the above equation,

Therefore, 0.125 gallons of the 35% acid solution Eli should add.

The equation is

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