Question

Andrew has a different cookie recipe that makes 28 cookies. He plans to have 21 guests at the party and wants each guest to have plenty of cookies. If he triples the recipe, how many cookies would each guest receive?

Answer 1

Answer: Since each recipe makes 28 cookies, tripling the recipe would give him 28(3) = 84 cookies.

Step-by-step explanation: Since each recipe makes 28 cookies, tripling the recipe would give him 28(3) = 84 cookies.

Then divide the total number of cookies by the number of guests:  84  21  = 4. Each person would get 4 cookies.

This process can be modeled by the expressions 28(3) ÷ 21 and  

28(3)

21

. This is because the fraction bar represents division.
