interest 5 1/2
%?

Answer 1

Given :-

Perimeter = 1880.9

Time = 1 years

Rate = 5 (½) years

To Find :-

Interest

Solution :-

SI = PRT/100

5½ = 11/2 %

» SI = 1880.9 × 11 × 1/2 × 100

» SI = 1880.9 × 11/200

» SI = 103.4

Answer 2

Formula for simple interest = total = start value x ( 1 + interest rate x time)

Total = 1880.90 x ( 1 + 0.055 x 1)

Total = 1,984.35

Interest = total - starting amount

Interest = 1984.35-1880.90 = 103.45

Interest: £103.45
