Andy’s total bill for lunch was$20. the cost of the drink was 15 percent of the total of the bill and the rest is the cost of the food. what percent of the total bill did andy’s food cost? what was the cost of his food?

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
