Practice makes perfect
If we borrow money from a bank, we pay the bank interest for the use of their money. Similarly, if we have an unpaid balance on a credit card, we also pay interest to the credit card company. To calculate the interest I, we use the simple interest formula.
I= p r t, where...
I& =Interest
p& = Principal
r& = Annual interest rate
t& = Time (in years)We are given that the loan amount is $ 725, the interest rate is 6.25 %, and the time is 1 year. We want to find the simple interest paid to the nearest cent. Keep in mind that 6.25 % is written in decimal form as 0.0625.
p= 725, r= 0.0625, t= 1
To calculate the interest, let's substitute these values into the simple interest formula and evaluate the right-hand side.
