A school has
83
third grade students,
107
fourth grade students, and
80
fifth grade students. Each table in the school cafeteria can seat
8
students.

Part A
Brennan says if all third graders are seated in the cafeteria, they would use
13
tables because
83
÷
8
=
10
with remainder
3
.
And
10
+
3
=
13
.

Explain whether Brennan is correct.
