Answer:
97.50 dollars
Explanation:
First add together all the brownies, then add together all the cookies.
123 brownies + 89 brownies = 212 brownies
56 cookies + 33 cookies = 89 cookies
Multiply the total amount of each bake sale treat to find the money made from each treat.
212 brownies at .25 cents each = 212 x .25
212 x .25 = 53
From brownies, girls made 53 dollars.
89 cookies at .50 cents each = 89 x .50
89 x .50 = 44.5
From cookies, girls made 44.5 dollars.
Next add how much money they made from each treat together to find the total amount of money earned
44.5 dollars
53.0 dollars
+ __________
97.5 dollars
