Answer:  $7,853.16</h3>
Work Shown:
A = P*(1+r/n)^(n*t)
A = 4750*(1+0.10/2)^(2*10)
A = 12,603.164099436
A = 12,603.16
That represents the account balance after 10 years. To find the interest only, subtract off the deposit amount.
interest = A-P = 12,603.16 - 4,750 = 7,853.16

Approx - 10% 
72 students signed up for canoeing + the 23 students who signed up for trekking + the 13 students who signed up for both = 108 students 
there are 120 students total, so you have to subtract 120 - 108 = 12 
Now to find the percentage, you have to divide the number of students who didn't sign up for either, by the total 
which is .1 = 10/100 = 10%
