Question

Find si and ci when principles not given shortcut formula

Answer 1

Answer:

Step-by-step explanation:

Calculate Accrued Amount (Principal + Interest) A = P(1 + r)t

Calculate Principal Amount, solve for P. P = A / (1 + r)t

Calculate rate of interest in decimal, solve for r. r = (A/P)1/t - 1.

Calculate rate of interest in percent. ...

Calculate time, solve for t.

Answer 2

Answer:

Calculate Accrued Amount (Principal + Interest) A = P (1 + r)t

Calculate Principal Amount, solve for P.

P = A / (1 + r)t

Calculate rate of Interest in decimal, solve for r.

r = (A / P) r/t - 1

Calculate rate of Interest in percent.

Calculate time, solve for it.
