Part A
P= beginning value
r= interest rate
n= #(number) of times per year interest is compounded

0 (1+.15/12)*48
I got the 48 by multiplying how many months there are in a year which is 12 and the part where it says the first fours it's active is 4.

I don't know part B you can try using the present value formula

Part A.
P is the amount Emma borrows: $300
r is the annual interest rate, expressed as a decimal: 0.15
n is the number of compoundings per year: 12


Part B.
Evaluating the formula with t=4, you have
  P(1 +r/n)^(nt) = 300(1 +.15/12)^(12*4)
  = 300(1.0125^48)
  = 544.61

Emma will owe $544.61 in 4 years.
