Answer:
17 13/24 cups of sugar
Step-by-step explanation:
Muffins = 5 3/8 cups of sugar
Brownies = 4 2/3 cups of sugar
Cookies = 7 1/2 cups of sugar
Total cups of sugar used = Muffins + Brownies + Cookies
= 5 3/8 + 4 2/3 + 7 1/2
= 43/8 + 14/3 + 15/2
= 129+112+180/24
= 421 / 24
= 17 13/24 cups of sugar
Equivalent to 17.5417 cups of sugar
Approximately about 18 cups of sugar to an whole number
