<span>3x^2 + 16x + 9 −16x − 12
= 3x^2 - 3

Since 1 person costs 50, and for each person after that the cost goes up by $5, we can conclude the following: There is a flat fee of $45 and each guest costs $5.
Since the entry fee is a flat charge and cannot change, and the amount per guest changes based on the number of guests, the variable goes after the 5.
This can be modeled as<em> $45 + $5x</em>. The only options that represent this are A and D. Since he wants his total to be under $100, The correct option would be <u>d. $45 + $5x < 100</u>. Otherwise, with answer A, he would come up with a total that goes over his limit.
- 52 x 1/5 + 4 = - 6.4
-12 x 1/5 - 4 = -6.4
The answer is 1/5
1) 1/7
2) 1/2
3) 1/9
4) 1/4
5) 1/3
6) 2/15
hope this helped:)

So multiply 5x6 to get 30
Then times 6x3 to get 18
Next times 4x9 to get 36
Add 30, 18, and 36 together to get
84
