Mindy and Troy combined ate 9 pieces of the wedding cake. Mindy ate 3 pieces of cake and Troy had .25 of the total cake.

Answer 1

Mindy and troy combined 9 pieces of the wedding cake.
Mindy ate = 3 pieces of cake
Troy = had ¼ of the total cake.
Now, let’s find an equation that will give us the total number of pieces of the cake
=> Let X = Mindy
=> let Y = Troy
=> Let c = total number of cake
=> X + Y = 9, where x = 9 and y = ¼
Let’s find the number of pieces of cake that Troy’s have:
=> Y = 9 – x
=> Y = 9 – 3 = 6
=> Y = 6
Now, let’s find the number of Cake
=> 6 = c/4
=> c = 4 x 6
=> c = 24
Thus, there are 24 cakes in all.

Answer 2

That's much Ado About Nothing.

Mindy --- 3
Troy (1/4)c, where c is the total number of pieces

(1/4)c + 3 = 9
(1/4)c = 6
c = 24
