Answer:
Go have fun at your Christmas party!
Multiple Choice= 2 points each
Short Response= 4 points each
Explanation:
You can set up a system of equations to find out how many points each type of question is worth.
x= multiple choice
y= short response
Equation 1 (You)
23x+10y=86
Equation 2 (Your Friend)
28x+5y=76
Solve with elimination. Multiply the second equation by negative 2 to cancel out the y-variable.
-2(28x+5y=76)
-56x-10y=-152
Subtract both equations together.
23x+10y=86
-56x-10y=-152
-33x= -66
x=2
Now that we found x, plug it into the first equation to solve for y.
23x+10y=86
23(2)+10y=86
46+10y=86
10y=40
y=4
Each multiple choice is worth 2 points, and each short answer response is worth 4 points.
