Answer:
d) 14 1/2
Explanation:
First, let's multiply 3(pinapple swirl cake) to find the total cups of flour for that.
3(2 1/3)=3(7/3)=3/1(7/3)=21/3=7
So, the total cups of flour for the pinapple cakes are 7 cups.
Next, let's find the chocolate cakes.
5(1 1/2)=5/1(3/2)=15/2=7 1/2
Add 7 1/2 and 7 together, and we get 14 1/2, or d)
