$1000 represents the principal amount invested by Loretta in her account
Simple interest is a quick and simple way to figure out how much money has accrued interest. Interest is always applied to the original principal amount and is calculated at the same rate for each period of time. Any bank where we deposit money will pay us interest on that amount. Simple interest is one of many types of interest that banks charge.
The formula for Simple interest is given by:
Simple interest = P*R*T/100
where P = principal amount invested
R = rate of interest
and T = time in years
Simple interest earned = 1100-1000 = 100
Substituting the values in the given formula:
100 = P*5*2/100
100 = 10P/100
P = 100*100/10
P = $1000
So, in the given question P represents the principal amount
