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

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257
