Question

A theater can seat 1015 people. The number of rows is 6 less than the number of seats in each row. How many rows of seats are there?

Answer 1

29 rows

Explanation:

r = # of rows = s - 6

s = # of seats/row

s(s - 6) = 1015

s² - 6s = 1015

s² - 6s - 1015 = 0 use the quadratic equation to find s (a=1, b=-6, c=-1015)

2 solutions of s: 35, -29 disregard the negative solution

r = s - 6 = 35 - 6 = 29

Answer 2

Answer:29 rows of 35 seats
