Mindy and troy combined ate 9 pieces are of wedding cake. mindy ate 3 pieces of cake and troy had 1/4 of the total cake. write an equation to determine how many pieces of cake (c) there was in total. find the total number of pieces of cake.

c/4 + 3 = 9

24

Step-by-step explanation:

The cake had a total of c number of pieces originally.

Mindy ate 3 pieces: 3

Troy ate 1/4 of the total cake: c/4

Combined, they ate: c/4 + 3

Combined they ate 9 pieces.

Therefore, c/4 + 3 must equal 9.

c/4 + 3 = 9

c/4 = 6

c = 24

The total number of pieces was 24.

Equation = 3 + 1/4c = 9 and Total cake pieces = 24
