So firstly, let's figure out the expression for a singular goody bag. Since there's 2 of each item, a single goody bag is going to be 
Now since we have 7 friends who are all getting 1 goody bag, multiply the cost of the goody bag by 7, and our expression is
. Now we can solve it from there.
Firstly, solve the multiplication inside the parentheses: 
Now add up what's inside the parentheses: 
Lastly, multiply and <u>your answer will be $56.56</u>
Answer:
63*
Step-by-step explanation:
The first thing you need to do is find the value of x. What I did for this was trial and error. I tried a number, and if it was too big, I tried a smaller one. If you add up all of the angles, it should equal up to 180*, so I kept on doing this until I added up to 180.
The answer I got was x=8, so I plugged this into the equation for A and solved. 9x8 is 72, and 72-9 is 63.
Therefore, 63 is the correct answer.
The correct answer should be A.
