Answer: $30 on decorations, $65 on food, $80 on party hall rental, $30 on prizes, and $45 on invitations.
Explanation:
Hello! You are told that she has spent $375.00. You know she spent $40 on costumes, $30 on prizes, $65 on food, $45 on candy, $80 on party hall rental, $40 on music, and $45 on invitations. You can fill what you know in for food, party hall rental, prizes, and invitations. You still don't know how much Mary spent on decorations though. To find this information out. Add all of the amounts that you already know and subtract the total from 375 to find the remaining amount Mary spent for decorations. 30 + 65 + 45 + 80 + 40 + 40 + 45 = $345. Subtract 345 from 375. 375 - 345 = 30. Your final answer is she spent $30 on decorations. Hope this helps you out! :)
