Bogdan [553]

Answer:

Step-by-step explanation:

the expression for compound interest is given as

$A = P(1 + \frac{r}{n})^{nt}$

A=$20,000

P=?

r=7.25%=0.0725

n=52 weeks

t=3 year

$20000= P(1 + \frac{0.0725}{52})^{52*3}\\\\20000= P(1 + \frac{0.0725}{52})^{156}\\\\20000= P(1 +0.00139)^{156}\\\\20000= P(1.00139)^{156}\\\\20000=1.2419P\\\\P=20000/1.2419\\\\P=16104.35\\$
