All of these scenarios involve money eamed through simple interest. Match each situation with the appropriate
simple interest formula.
For 10 years
1 = (200)(0.04)(10)
$200 was invested at 4%.
For 4 years
$100 was saved at a rate of 2%.
1 = (400)(0.10)(2)
For 2 years
$400 earned interest at a rate of 10%.
1 = (100)(0.02)(4)
