  2. Ch. 5 Review Solve for x: Half-Life Suppose a culture of 750 bacteria are out in a petri dish and the culture doubles every hour. Find when the number of bacteria will be 500,000. Solve algebraically. Find when the number of bacteria will be 7 times their initial size. Solve algebraically.

  3. Ch. 5 Review Word Problems!! Your goal is to save $500,000 in 35 years. If you put $500 in an account every month, at what interest rate will your account need to be compounded monthly in order to reach your goal? • Compare the values of a $5,000 investment compounded quarterly for 5 years with the same investment compounded daily at 6.5% APR.

  4. Ch. 5 Review • Consider a $225,000 mortgage loan with interest at 5% APR compounded monthly. • What is the monthly payment amount required to pay off the loan in 30 years? • If you pay $250 more per month, how long will it take to pay off the loan? • Consider a $500,000 mortgage with a 30 year loan and interest at 7.5% APR compounded monthly. • What is the monthly payment amount required to pay off the loan in 30 years? • If you pay the required monthly payment for 12 years and then pay $1000 more each month than the monthly payment until the loan is paid, how long will it take to pay off the house? How much do you pay the bank?
