Answer:
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
