Answer:
2 sweatshirts per student
Step-by-step explanation:
I'm not sure whether or not I understood this problem correctly, but I tried my best. Try to make your questions more clear in the future.
($35 per ticket * 16 students) + ($19 per sweatshirt * X sweatshirts sold) = $960
$560 from the sweatshirt + 19X = 960
19X = 960 - 560 = $400
X = 21 sweatshirt sold overall
Number of sweatshirt sold per student = 21/19 = 1.105 ---> 2 per student

Answer:
D. 39°
Step-by-step explanation:
mAB = (3x + 9°)
mCD = (11x – 71)
From the diagram: |AB|=|CD|
Since arcs AB and CD are subtended by a chord of equal length.
mAB=mCD
3x + 9°=11x – 71°
Collect like terms to solve for x
11x-3x=9°+71°
8x=80°
x=10°
Therefore, the measure of AB:
mAB = (3x + 9°)
=3(10)+9
=30+9
=39°
The correct option is D.
