Answer:

$3250

Step-by-step explanation:

The formula for simple interest is:

[tex]i=Prt[/tex]

Where

i is the simple interest earned

P is the principal (initial amount) invested

r is the rate of interest (in decimal)

t is the time in years

Given, 1.25% simple interest, in decimal, that is:

1.25/100 = 0.0125

r = 0.0125

and

i = 812.50

t = 20

Substituting, we find P:

[tex]i=Prt\\812.50=P(0.0125)(20)\\812.50=P(0.25)\\P=\frac{812.50}{0.25}\\P=3250[/tex]

The principal he invested was $3250
