Mindy and troy combined ate 9 pieces of the wedding cake. mindy at 4 prices of cake and troy had 1/4 of the total cake. write an equation to determine how many pieces of cake (c) there were in total

24 pieces total.

Step-by-step explanation:

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:

m

+

t

=

9

We also know Mindy ate 3:

m

=

3

and Troy ate

1

4

of the total number:

t = tot

/

4

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

his chances of getting a coin of higher value is 4/19
