Use PMT \( =\frac{p\left(\frac{r}{n}\right)}{\left[1-\left(1+\frac{r}{n}\right)^{-m}\right]} \) to determine the regular payment amount, rounded to the nearest dollar. Your credit card has a balance of \( \$ 5900 \) and an annual interest rate of \( 12 \% \). You decide to pay off the balance over three years. If there are no further purchases charged to the card, a. How much must you pay each month? b. How much total interest will you pay? a. The monthly payments are approximately \( \$ \square \). (Do not round until the final answer. Then round to the nearest dollar as needed.) b. The total interest paid over 3 years is approximatsily \( \$ \square \). (Round to the nearest dollar as nesded.)

A car was valued at \( \$ 31,000 \) in the year 1995 . The value depreciated to \( \$ 11,000 \) by the year 2003. A) What was the annual rate of change between 1995 and 2003 ? \( r=\square \) Round the rate of decrease to 4 decimal places. B) What is the correct answer to part A written in percentage form? C) Assume that the car value continues to drop by the same percentage. What will the value be in the year 2007 ? value \( =\$ \)

On September 5, Zhu Company buys merchandise on account from Gao Company. The selling price of the goods is \( ¥ 15,000 \), and the cost to Gao Company was \( ¥ 8,000 \). On September 8 , Zhu returns defective goods with a selling price of \( ¥ 2,000 \) and the fair value of \( ¥ 300 \). Record the transactions on the books of Gao Company. Sept. 5 Sept. 5

QUESTION 8 A new cell phone was purchased for R 7 200. Determine the value of the cell-phone after 3 years if it depreciates at \( 25 \% \) per annum on Reducing Balance scale. \( A=P(1-i)^{n} \)

A nominal interest rate of \( 7,2 \% \) per annum is quoted. The interest is compounded monthly. 8.3.1 Calculate the effective interest rate n a round off to a whole number.

An amount of R 500 is invested at \( i \% \) per annum compound interest. After 6 years it has grown to \( \mathrm{R} 1126,10 \). Calculate the value of \( i \), round off to a whole number and give your answer as a percentage.
