Step-by-step explanation:
Let x be the number of students in the class
12% failed and the number of students is 3

Answer:
(E) 450
Step-by-step explanation:
Let x represent the number of gallons of solution X that must be added to the mix. Then the amount of sugar in the mix is ...
0.20x +0.40·150 = 0.25(150 +x)
0.20x +60 = 37.5 +0.25x . . . eliminate parentheses
22.5 + 0.20x = 0.25x . . . . . . subtract 37.5
22.5 = 0.05x . . . . . . . . . . . . . subtract 0.20x
450 = x . . . . . . . . . . . . . . . . . . multiply by 20
450 gallons of solution X must be added to make a 25% sugar solution.
