Question

Alexis and Martin helped the school set chairs in rows for an assembly. They put the same number of chairs in each row. Using 92 chairs available, Alexis made 4 rows with 2 chairs left over while Martin made 5 rows with no chairs left over. Write and solve an equation that can be used to find the number of chairs in each row.

Answer 1

4c + 5c = 92 - 2

9c = 90

c = 10

22 chairs were not used in the assembly.
