Sarah wants to buy a brand-new television in the future, so she deposits $50 weekly into an account with an interest rate of 1.3%/a compounded weekly. How much money will Sarah have in 5 years? How much will need to be in a pension plan which has an interest rate of 5% compounded quarterly if you want a payout of $1300 quarterly for the next 28 years? After buying a state-of-the-art television, Jane makes an agreement with the store to pay $100 weekly for the next 4 years, financed at an interest rate of 10.4%/a compounded weekly. What is the cash value of the television right now
