Answer: I got 3
Step-by-step explanation:
14 + 14 + 14 would give you 42. 28x20x24 = 23,520. (The original volume was 7,840) If you do 7,840x3 you would get 23,520 so the new volume would be 3 times higher
3 = 10%
15 = 50%
30 = 100%
30 * 1.5 = 45

The two inequalities formed will be:
One for ticket quantity:
x + y ≤ 600
One for funds generated via tickets:
5x + 7y ≥ 3500
Equating x to 330,
5(330) +7y ≥ 3500
y = 265
Checking if the other inequality holds true:
330 + 265 ≤ 600
595 ≤ 600
This inequality is still true so they can sell 265 tickets on the event day and cover their expenses.
So to solve you need to set up equations, Using h as the height. So the base is 9 inches more (+9) than 3 times the height (3h) so 3h+9 equals the base. You have the area so you need to plug in the equation for the base and h for height and divide it all by 2. h(3h+9)/2=105. after you solve that and get h by itself you should get h= 7 and the b= 30
