Question 1166486: Find the number of gallons of a 15% acid, 75% acid, and 60% that are required to make 100 gallons of 51% acid. If the sum of three times the number of gallons of a 15% acid and a 75% acid is thirty more than the number of gallons of 60% acid? Answer by josgarithmetic(39617) (Show Source):
CONCENTRATION% VOLUME PURE Acid
15 x 0.15x
60 j 0.6(3x+3y-30)
75 y 0.75y
51 100 0.51*100
This part seems unclear: "If the sum of three times the number of gallons of a 15% acid and a 75% acid is thirty more than the number of gallons of 60% acid"
