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
