Answer:
1). 875 seats
2). 25 rows in each section
3). $8400
4). Saving of $360
5). 2105 tickets remained unsold
6). x = 16
Since the scale factor is 3:1 you can multiply the length of the side of the triangle to the right by 3 to make the ratio 3:3
the equation would be:
2x+5 = 45
subtract 5 from both sides
2x = 40
divide both sides by 2
x = 20
hope this helps
