Q. Arun was out at a restaurant for dinner when the bill came. He wanted to leave a tip of 10% 10 \% . What number should he multiply the cost of the meal by to find the total plus tip in one step?\newlineAnswer:
  1. Understand the problem: Understand the problem.\newlineArun wants to leave a 10%10\% tip on the cost of his meal. To find the total cost including the tip, he needs to add the tip to the original cost of the meal. The tip is 10%10\% of the meal's cost, so we need to express the total cost as a percentage of the original cost.
  2. Express as percentage: Express the total cost as a percentage.\newlineThe original cost of the meal is 100%100\% of itself. A 10%10\% tip means that the tip is 10%10\% of the original cost. To find the total cost including the tip, we add the original cost (100%100\%) and the tip (10%10\%) together.\newline100%+10%=110%100\% + 10\% = 110\%
  3. Convert to decimal: Convert the percentage to a decimal.\newlineTo use this percentage to find the total cost in one step, we convert the percentage to a decimal. To do this, we divide the percentage by 100100.\newline110%÷100=1.10110\% \div 100 = 1.10
  4. Find total cost: Use the decimal to find the total cost.\newlineArun should multiply the cost of the meal by 1.101.10 to find the total cost including the tip.
