Answer:
c(X)=R(X)
125x+18000=215x

18000=90x (divede both sides by 90)
X=200

Step-by-step explanation:
Amount paid by customer to fly to California if carrying 2 pieces or less than 2 pieces of luggage for which they won't be charged for = $439
Fee for additional luggage = $25
Fee for additional luggage if an individual carries p luggages = 25(p - 2)
Total amount (C) if p pieces of luggage were carried by a customer travelling = fee for additional p pieces of luggage + $439
The function for this would be:

If there are 4 chocolate chip cookies and 7 peanut butter cookies in each gift box, you will need to multiply the price, c/p, by the number of cookies. This will give you:
4c + 7p
Now if you wanna find how much <em>5 </em>gift boxes cost, you'll need to multiply that expression by 5. Put parenthesis around 4c + 7p, and add a 5 before the first parenthesis. That will bring you to the answer:
<h2>5(4c + 7p)</h2>
