Q. Bo was out at a restaurant for dinner when the bill came. To find the total plus tip, he multiplied the cost of the meal by 1.17 . What percent tip did he leave?Answer: %
Understand the problem: Understand the problem.Bo multiplied the cost of his meal by 1.17 to get the total plus tip. The number 1.17 represents the original cost of the meal (which is 100%) plus the tip percentage. To find the tip percentage, we need to subtract the original 100% from 117%.
Calculate the tip percentage: Calculate the tip percentage.Tip percentage = Total percentage - Original cost percentageTip percentage = 117%−100%Tip percentage = 17%
Check the calculation: Check the calculation for any mathematical errors.117% represents the total cost (meal + tip), and 100% represents the original cost of the meal. Subtracting these gives us the tip percentage.17%=117%−100%, which is correct.
