Formula

Interest formula I=Prt To find the interest multiply the Principle (the money borrowed or lent) by the Rate (the percent as a decimal) by the Time (in years.) I found a \$1500 stereo on sale for \$1000! If I finance for 25% simple interest and pay for 3 years, how much is the interest? 1000x.25x3 = 750 How much do I pay back altogether? \$1750

Interest formula I=Prt To find the interest multiply Principle x Rate x Time I found a \$1500 stereo on sale for \$1000! If I finance for 25% simple interest and pay for 3 years, how much is the interest? 1000 x 0.25 x 3 = #750 How much do I pay back altogether? \$1750
