There is at least one coin of each denomination and a different quantity of coins of each denomination. Also, if the different denominations are ordered by their quantities of coins, the first quantity will be a divisor of the second quantity and the second quantity will be a divisor of the third quantity. Find the maximum amount of money, in Colones, that could be inside the bag. Write your answer correct to 3 significant figures.

This question awards 100 ! i really don’t want to fail i will also mark you !

The rate of decay of a radioactive substance depends upon the amount present initially. the mass y (mg) of the radioactive substance cobalt-60 present in a sample at time t (years) is represented by the exponential equation y=50e −0.1315 t . answer the following questions in complete sentences. 1. how does the exponential equation above compare to the equation for simple interest that is compounded continuously? explain the similarities. 2. what is the initial amount of cobalt-60 in the sample? 2. how much cobalt-60 is left after 8.4 years? show your work. 3. what would be the y-intercept of the graph? what does it represent? 4. after how many years will the amount of cobalt-60 left be 6.25 mg? explain what happens to the cobalt-60 after 50 years? 5. discuss some “real-world” examples and uses of cobalt-60
