Question

amount = 2000 ( 1 + 15/100) square x (1+(1/3x15)/100)

Answer 1

$2000(1 + \frac{15}{100} ) ^{2} \times (1 + \frac{ \frac{1}{3} }{100} \times 15) \\ = 2000(1 + \frac{225}{10000} + \frac{3}{10} ) \times (1 + \frac{15}{300} ) \\ = 2000 \times \frac{13225}{10000} \times \frac{315}{300} \\ = \frac{26450}{10} \times \frac{315}{300} \\ = \frac{8331750}{3000} \\ = 2777.25$
