Hachalu is a senior college student. He owns a car that has a market value of 500,000 birr. He also has different personal properties in his rented home. He wears disposable contact lenses which costs him 800 birr every year. Moreover, he runs every day for 30 minutes in a nearby public park that has a track record of being dangerous because of drug dealers and purse-snatchings. His parents are working hard to support his tuition fee.
 If Hachalu potentially faces the following risks, which risk handling tools will be the appropriate? Explain your answer appropriately 
 1)Physical damage to his car because of collision with another car 
2)Liability lawsuit against him because of negligent operation of his car 
3) Total loss of his personal properties because of fire
4)Disappearance of his disposable contact lenses 
5)Physical assault on Hachalu by drug dealers in the area where he runs

6)Loss of tuition fee helps because his father is killed by a drunk driver in car accident

A math camp instructor estimates that students will take 3 hours to complete the first assignment of math puzzles, but will be able to improve at a rate of 0.95 for the second assignment (they will take 5% less time). If they are able to sustain this rate of improvement, how long will students take to complete the fourth assignment.
