Whole numbers solving Problems: FINANCE Nyakallo checks the newspaper and sees that the exchange rate between the South African rand ( R) and the Kenyan shilling (K) is R \( 1=\mathrm{K} 10 \). 1. Choose the exchange rate that represents a weaker rand (against the shilling). Answer: R \( 1=\mathrm{K} 5 \) R \( 1=\mathrm{K} 13 \) R \( 2=\mathrm{K} 20 \) Final check

To determine which exchange rate represents a **weaker** South African rand (R) against the Kenyan shilling (K), let's analyze each option based on the initial exchange rate provided: **Initial Exchange Rate:** - **R 1 = K 10** This means that **1 Rand** is equivalent to **10 Kenyan Shillings**. A **weaker rand** implies that each rand buys **fewer** Kenyan shillings compared to the initial rate. Let's evaluate each option: 1. **Option A: R 1 = K 5** - **Analysis:** Here, 1 Rand buys only 5 Kenyan Shillings. - **Conclusion:** Since each rand now buys fewer shillings than before (5 < 10), the rand has **weakened**. 2. **Option B: R 1 = K 13** - **Analysis:** Here, 1 Rand buys 13 Kenyan Shillings. - **Conclusion:** Each rand now buys more shillings than before (13 > 10), indicating the rand has **strengthened**. 3. **Option C: R 2 = K 20** - **Analysis:** This can be broken down to R 1 = K 10. - **Conclusion:** This rate is **identical** to the initial exchange rate, so the rand's value remains **unchanged**. **Final Decision:** - The exchange rate that represents a **weaker rand** is: **Answer:** **R 1 = K 5**
