Given
Angelo drew a model with his drawing length 10 inches tall
The actual pole length is 15 feet tall
drawing scale is the ratio of drawing length to the actual length i.e.
X gallons of a 60% acid solution contains 60%×x=0.6x gallons of acid.
50 gallons of a 24% acid solution contains 24%×50=0.24×50=12 gallons of acid.
After mixing, there will be x+50 gallons of a solution, and 0.6x+12 gallons of acid. The concentration must be 50%, so the volume of acid divided by the volume of the solution is 50%, or 0.5.
The answer is A. 130 gallons.
