Answer:
You would need 36 gallons of 65% sugar solution
Step-by-step explanation:
You can always solve these problems with a proportion
The numerator will represent the amount of sugar, the denominator will represent the amount of solution.
First, we have (.4 * 114 = ) 45.6 gallons of sugar.

Its to scale. so every inch is 1.5 feet according to the statement of 18 inches being equal to 27 feet. In that case, the answer is C. because 20X1.5 is 30
