Question

Andy's total bill for lunch is is $20 .The cost of the drink is 15% of the

total bill and the rest is the cost of the food .What percent of the total bill did Andy's food cost ? What is the cost of the food?

Answer 1

100%-15% = 85%
Food cost = 85%
20*0.85 = $17
Food cost = $17

Answer 2

So,

Andy paid $20 total for his lunch (100%).

15% is for drink.

Therefore, 100 - 15 = 85% is the percent that was constituted by the food.

85% of 20 is equal to 0.85 * 20 is equal to:


`(17)/(20) *20= (17*20)/(20) = 17`

Andy's food cost $17.
