Q. Tyshawn was out at a restaurant for dinner when the bill came. He wanted to leave a tip of 28%. What number should he multiply the cost of the meal by to find the total plus tip in one step?Answer:
Understand the problem: Understand the problem.Tyshawn wants to leave a 28% 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. This can be done in one step by multiplying the cost of the meal by a certain number.
Convert to decimal: Convert the percentage to a decimal.To work with percentages in calculations, we convert them to decimals. A 28% tip is the same as 0.28 in decimal form.
Determine multiplier: Determine the multiplier for the total cost including tip.To find the total cost including the tip, we add 1 (which represents the original cost of the meal) to the decimal form of the tip percentage. So the multiplier will be 1+0.28.
Calculate total cost: Calculate the multiplier.1 (original cost) + 0.28 (tip) = 1.28So, Tyshawn should multiply the cost of the meal by 1.28 to find the total cost including a 28% tip.
