Since out of 5 sections in Economics 3 are full, there are only 2 remaining sections available for Jessica to choose from.
I think this is a combination:
n = 2 + 4 + 3 + 2 = 11
r = 1 + 1 + 1 + 1 = 4
nCr = n! / r!(n-r)! = 11! / 4!(11-4)! = 11! / 4! * 7! = 330
Jessica can have 330 different sets of classes to take.

Answer:
The total number of albums sold on the first day=34
Step-by-step explanation:
Derive expressions for the number of albums sold
each day;
Let;
the total number of albums sold on the first day=x
the total number of albums sold on the second day=y
but,
total number of albums sold on the second day is twice the total number of albums sold on the first day, therefor=, y=2×x= 2 x
The total number of albums sold for the two days can be expressed as;
Total sales=number sold on the first day+number sold on second day
where;
Total sales=102
number sold on the first day=x
number sold on second day= 2 x
replacing;
(x+2 x)=102
3 x=102
x=102/3
x=34
The total number of albums sold on the first day=34
x = Original Price = $775
y = Coupon Value = $125 (this is the amount you save)
z = Final Price = x-y = 775 - 125 = 650
<h3>Answer: Choice D. $650 </h3>
