The balance in Accounts Receivable was \( \$ 690,000 \) at the beginning of the year and \( \$ 750,000 \) at the end of the year. Credit sales for the year totaled \( \$ 4,100,000 \). During the year, \( \$ 450,000 \) in customer accounts were written off. How much cash was collected from customers during the period? A. \( \$ 4,040,000 \) B. \( \$ 3,590,000 \) C. \( \$ 4,490,000 \) D. \( \$ 4,610,000 \)

Suppose that \( \$ 59,000 \) is invested at \( 4 \frac{1}{2} \% \) interest, compounded quarterly. a) Find the function for the amount to which the investment grows after \( t \) years. b) Find the amount of money in the account at \( t=0,2,6 \), and 10 years. a) The function for the amount to which the investment grows after t years is \( \mathrm{A}(\mathrm{t})= \) (Simplify your answer. Type an expression using t as the variable.) b) Find the amount of money in the account at \( \mathrm{t}=0,2,6 \), and 10 years. The amount of money in the account at \( \mathrm{t}=0 \) years is \( \$ \square \). (Round to the nearest dollar as needed.) The amount of money in the account at \( \mathrm{t}=2 \) years is \( \$ \square \). (Round to the nearest dollar as needed.)

An OB/GYN physician in private practice knows her malpractice insurance will be \( \$ 90,000 \) and is due in one year. How much should she deposit into an account each month if that account has an annual rate of \( 3.3 \% \) compounded monthly and she wishes to pay it in full knowing that the insurance company drops the price by \( 2 \% \) if paid in full? Round your answer to two decimal places. Do not include the \( \$ \) sign in your answer. Hint: Lower the price by \( 2 \% \) as she is planning on paying in full.

A corporation estimates it will need \( \$ 3,000,000 \) in 6 years to replace its existing machinery. How much should it deposit each quarter at an annual rate of \( 5.5 \% \) compounded quarterly to meet this obligation? Round your answer to two decimal places. Do not include the \( \$ \) sign in your answer. Your Answer: Answer An OB/GYN physician in private practice knows her malpractice insurance will be (1 point) Retake question

\[ \text { Find the future value of each deposit if the account pays (a) simple interest, and (b) interest compounded annually. } \] \[ 300 \text { at } 6 \% \text { for } 3 \text { years } \]
