A theater can seat 228 people. The number of rows is 7 less than the number of seats in each row. How many rows of seats are there?

Answer 1

r= s -7

r+s = 224

r = 224-s = s-7

2s =231

s = 115 1/2 seats per row,

r = 108 1/2 rows

which doesn't really make sense to have fractional rows and fractional seats
