Accepted Solution

A:

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 = $9932.00Now, 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%
