Answer: 10, 15
Step-by-step explanation:
Given
Stephanie wants to raise at least $800
she plans on selling VIP tickets for $20 each and general admission for $40 each
suppose there are x and y tickets for VIP and general admission

solving above two inequality
Stephanie must sell 10 tickets for VIP and 15 tickets for general admission
14. (2x - 1)(x + 7) = 0Using the zero factor property, we know that either the first or second terms (or both) must be equal to 0 if their product is 0. We can set each term equal to 0 to find the solutions:
2x - 1 = 0
2x = 1
x = 1/2
x + 7 = 0
x = -7
15. 
To solve this equation, you first need to set it equal to 0:

Next, it can be factored:

Finally, we can solve just like we did above:
x + 5 = 0
x = -5
x - 2 = 0
x = 2
16. 
First, you can simplify by dividing each side by 4:

Now, set the equation equal to 0:

Next, factor:

Finally, find the solutions:
x + 5 = 0
x = -5
x - 5 = 0
x = 5
0.7/729 equals 0.00088383838
