Show enough work so I can tell what formula you used and what you stuck in it. 1) Ariana's daughter is about to head off to college. She wants to set up an account from which her daughter can withdraw $400 a month for the next 4 years. How much will she need to put in the account at the beginning, if the account earns 3% interest? 2) Scott and Samantha received 53000 in cash gifts at their wedding (or at least that's what was left after the honeymoon in Vegas). If they invested that money in an account earning 6% compounded quarterly, how much will they have towards a down payment on a house 5 years later? 3) You really want a new hot tub that costs $4,000. a. If you have an account earning 6% interest, how much would you need to save every month for the next 2 years to buy the hot tub? b. If you buy the hot tub on a credit card with a 16% APR, how much will your monthly payments need to be to pay it off in 2 years
