Answer:  13%

Step-by-step explanation:

We know that the formula to find the simple interest :

[tex]I=Prt[/tex], where P is the principal amount , r is rate (in decimal )and t is the time period (in years).

Given : Albert borrowed $19,100 for 4 years. The simple interest is $9932.00. Find the rate.

i.e. P = $19,100 and  t= 4 years and I = $9932.00

Now, Substitute all the values in the formula , we get

[tex]9932=(19100)r(4)\\\\\Rightarrow\ r=\dfrac{9932}{19100\times4}\\\\\Rightarrow\ r=0.13\ \ \ \text{[On simplifying]}[/tex]

In percent, [tex]r=0.13\times100\%=13\%[/tex]

Hence, the rate of interest = 13%
