Smells like team spirit. A losing basketball team at your school has recently suffered a large slump in attendance at games. Suppose 1200 students attended the first game, 1150 attended the next game, 1100 attended the game after that, and this pattern continues for several more games. Write a formula that matches this pattern, giving the number of students attending a game, y, in terms of the number of games since the first game, x. So when

If $5,000 is deposited in an account that receives 6.1% interest compounded continuously, how much money is in the account after 6 years? 2. After how many years will an account have $12,000 if $6,000 is deposited, and the account receives 3.8% interest compounded continuously? 3. Abigail wants to save $15,000 to buy a car in 7 years. If she deposits $10,000 into an account that receives 5.7% interest compounded continuously, will she have enough money in 7 years? 4. Daniel deposits $8,000 into a continuously compounding interest account. After 18 years, there is $13,006.40 in the account. What was the interest rate? 5. An account has $26,000 after 15 years.
