<span>f(x)=3x+8 and g(x)=6x+6 (f+g)(x) = f(x) + g(x) = (3x+8) + (6x+6) = 9x + 14 Then (f+g)(−1) = 9(-1) + 14 = 5 f(x)=6x+4 and g(x)=3x+7 (f+g)(x) = f(x) + g(x) = (6x+4) + (3x+7) = 9x + 11 Then (f−g)(1) = 9(1) + 11 = 20</span>

Answer:

They can invite 136 while staying in budget

Step-by-step explanation:

Firstly, you know they will have to pay an $80 cleaning fee, therefore, you can subtract 80 from 5,000:

5,000-80 = 4,920

After doing this, you can take 4,920 and divide it by 36 (the price per person).

4,920/36 = 136.67

Because you can not have .67 of a person, your closest number you can use is 136.

leaving them with $24
