Cassie bakes cookies and brownies for the school bake sale. Each cookie will sell for $0.50 and each brownie will sell for $0.75

katovenus [111]

T= total money raised
c= # cookies sold
b= # brownies sold

Total money earned equals the price per cookie times number of cookies sold plus the price per brownie times the number of brownies sold.

T= ($0.50 * # c) + ($0.75 * # b)

T= $0.50c + $0.75b

ANSWER: The expression showing money earned is T= $0.50c + $0.75b

Hope this helps! :)
