##### 2 Answers

24 pieces total,

R = 3tot/4-3

#### Explanation:

m = Mindy

t = troy

tot = total number of pieces

R = remaining amount

So we know that Mindy and ate a combined number of thirteen pieces:

We also know Mindy ate 3:

and Troy ate

t = tot

so after combining:

3 + tot/4 = 9

now we solve for tot:

tot/4 = 6

tot = 24

So there is a total of 24 pieces.

R = tot - (tot/4+3)

R = 3tot/4-3

R = 15

First, we need to find out how many pieces of cake Troy ate.

If Mindy and Troy at

where cake is equal to

So,

The total number of pieces of cake is
