the answer is either A or B, probably C, maybe D. I know it's one of those
Lets make a known and an unknown chart:
KNOWN: Fifteen $5 bills.
UNKNOWN: How much is that?
So to find the answer to this, we are going to do 5+5+5+5+5+5+5+5+5+5+5+5+5+5+5=??
The answer is $75.
~Hope I helped!~
Divide them
We'd get
2n^2+1/10n + 1
I think the answer is 32 if I did my math right sorry if it wrong
