1. Suppose $3,000is invested at48% compoundedmonthly(i.e.,12times a year). (a) What will the accumulated amount be after6years? Exact accumulated amount (without using a calculator) = ? dollars

Accumulated amount, rounded to 2 decimal places = ? dollars

(b) How much interest accrued during the6years? Interest, rounded to 2 decimal places = ? dollars

2. Suppose $8,000 is invested at 9% compounded continuously. (a) What will the accumulated amount be after 5 years? Exact accumulated amount (without using a calculator) = ? dollars

Accumulated amount, rounded to 2 decimal places = ? dollars

(b) How much interest accrued during the 5 years?

Interest, rounded to 2 decimal places = ? dollars

3. Determine the interest rate r needed for an investment of $4,000 to grow to $7,000 in 9 years if interest is compounded continuously. Exact interest rate (without using a calculator), r = ?

Interest rate, as a percent, rounded to 2 decimal places = ? %

5. Determine the interest rate r needed for an investment of $5,000 to grow to $35,000 in 6 years if interest is compounded quarterly (i.e., 4 times a year). Exact interest rate (without using a calculator), r = ?

Interest rate, as a percent, rounded to 2 decimal places = ? %

5. Determine the interest rate r needed for an investment to triple in value in 17 years if interest is compounded continuously. Exact interest rate (without using a calculator), r =

Interest rate, as a percent, rounded to 2 decimal places = ? %
