A deposit of $100,000 is placed in an account that pays 7.6% interest per year compounded quarterly.  The inflation rate is 3.6% per year.  The account is left undisturbed for 15 years.   How much money will be in the account? What will be the purchasing power in terms of today’s dollars? What is the real rate of return that is made on the account?

The interest on a particular savings account is compounded continuously. The account initially had $2,200 deposited in it. The worth of the account after t-years can be calculated using the formula: A(t)=2200e0$1 (a) By what percent will the worth of the account increase per year? Round to the nearest hundredth of a percent. (b) To the nearest tenth of a year, how long will it take for the worth of the account to triple? (c) If another investment began with a principal of $2,500 and earned simplest interest of 3.8% applied once per year, which investment would be worth more after 10 years? Justify

Suppose $8,000 is invested in an account with an annual interest rate of 4.7% per year, compounded monthly. How much money will be in the account after 35 years? $ Round your answer to the nearest penny. How long will take for the investment to double? years. Round to two decimal place.

Suppose we invest £100,000 at a semi-annually compounded interest rate of 6% for 1 year. What are the gross and net returns? Do the same if this was a monthly compounded rate and a continuously compounded rate. Compare the three net returns to the interest rate. Can you explain the ordering of these 4 quantities?
