14. James invests a total of \( \$ 32,000 \) in two accounts. The first account earned an annual interest rate of \( 6 \% \) and the second account earned an annual interest of \( 3 \% \) . At the end of one year, the total amount of money gained was \( \$ 1,380.00 \) . How much was invested into each account? 

QUESTION 2 Boitumelo invests an amount of R28 000 for a period of 7 years. For the first two years the interest was \( 12 \% \) p.a. compounded semi-annually. The interest was then changed to \( 10 \% \) p.a. compounded quarterly. Determine the value of the investment after the 7 -year period. \( 2.2 \quad \begin{array}{l}\text { Convert an interest rate of } 10 \% \text { p.a. compounded quarterly to an annual effective (3) } \\ \text { interest rate. }\end{array} \) \( 2.3 \quad \begin{array}{l}\text { A lawnmower was traded in for R236 after } 10 \text { years. The depreciation was } \\ \text { calculated at } 9.2 \% \text { p.a. on a straight-line basis. } \\ \text { Determine the cost of the lawnmower } 10 \text { years ago. }\end{array} \)

Boitumelo invests an amount of R28 000 for a period of 7 years. For the first two (3) years the interest was \( 12 \% \) p.a. compounded semi-annually. The interest was then changed to \( 10 \% \) p.a. compounded quarterly. Determine the value of the investment after the 7 -year period.

8. The rule \( V_{n}=6000 \times 1.09^{n} \) could be used to model which of the following scenarios? A. An investment of \( \$ 6000 \) with an interest rate of \( 0.09 \% \) p.a, compounding monthly. B. An investment of \( \$ 6000 \) with an interest rate of \( 0.09 \% \) p.a, compounding quarterly. C. An investment of \( \$ 6000 \) with an interest rate of \( 9 \% \) p.a, compounding monthly. D. An investment of \( \$ 6000 \) with an interest rate of \( 9 \% \) p.a, compounding annually. 9. Find the final value of each of the following investments, compounding yearly, correct to the nearest cent. a. \( \$ 120 \) invested for three years with compound interest of \( 5 \% \) per annum. b. \( \$ 9000000 \) invested in a compound interest account for five years at \( 8.2 \% \) per annum. c. \( \$ 230000 \) invested in a compound interest account for twenty years at \( 2.31 \% \) per annum.

A, B को 600 रु. 2 वर्षों के लिए एवं C की 150 रु. 4 वर्षों के लिए उधार देता है तथा \( A^{\prime} \) दोनों से एक साथ 90 रु. साधारण ब्यांज के रूप में प्राप्त करता है। ब्याज की दर ज्ञात करें। \( \begin{array}{ll}\text { (1) } 5 \% & \text { (2) } 3 \% \\ \text { (3) } 6 \% & \text { (4) } 7 \%\end{array} \)
