131 apples were sold on Saturday and Sunday.
Work:
Monday - Friday : 5 days
20 x 5 = 100 apples
Monday - Sunday: 7 days
33 x 7 = 231 apples
231 - 100 = 131
Using the formula A=P(1+i/100)^n
where A is the investment/loan after n years, P is the original investment/loan and i% is the interest per annum.
A=5000(1+0.05)^48
A=52006.35
