We have a couple of milkweed plants in our front yard. For the past couple of years, there have been very few caterpillars and of those there have been very few that lived to be butterflies. IT was the assasin bugs that did it, we think. But this year, something weird happened. After all of the assasin bugs disappeared in about November, a bunch of caterpillars popped up. I mean a bunch! The only problem - it's December! Luckily, I live in the south, but tonight is cold, so I took as many as I could find inside to keep warm, but I dont know how much good it will do...What should I do?

1) A company placed $1,000,000 in three different accounts. It placed part in short-term notes paying 4.5% per year, twice as much in government bonds paying 5%, and the rest in utility bonds paying 4%. The income after one year was $45,500. How much did the company place in each account?

2) A stadium has 49,000 seats. Seats sell for $25 in Section A, $20 in Section B and $15 in Section C. The number of seats in Section A equals the total number of seats in Sections B and C. Suppose the stadium takes in $1,052,000 from each sold-out event. How many seats does each section hold?

3) A change machine contains nickels, dimes and quarters. There are 75 coins in the machine, and the value of the coins is $7.25. There are 5 times as many nickels as dimes. Find the number of coins of each type in the machine.
