Question

WILL MARK BRAINIEST PLEASE HELP: For the grand opening of her store, Rosemary is making 200 cupcakes. The recipe calls for 6 cups of flour to make 40 cupcakes. Russell is helping Rosemary by making an additional 200 cupcakes using a different recipe. His recipe calls for 10% more flour than Rosemary’s recipe and makes 40 cupcakes. What is the total amount of flour that Russell and Rosemary need to make all 400 cupcakes? PLEASE SHOW YOUR WORK

Answer 1

Rosemary should use 5 times the amounts in the recipe, since she needs 200 cupcakes. As such, she'll require 5*6=30 cups.
Since Russell uses a bit more, 10% more flour, he'll need 110% of 30 cups for the same amount of cupcakes, so he'll need: 1.10*30=33 cups of flour.
In total, the whole project will require 30+33= 63 cups of flour
