Atheater can seat 550 people. the number of rows is 3 less than the number of seats in each row. how many rows of seats are there?

The number of rows will be a divisor of 550 such that the quotient is 3 more.

... 550 = 1×550 = 2×275 ≈ 5×110 = 10×55 = 11×50 = 22×25

Factors 22 and 25 differ by 3.

The number of rows of seats is 22.

The number of seats in a row is 25.
