Question 1 1.1.1 Express in years the total repayment period for this offer. Step 1: Identify the repayment period in months. The repayment period is 42 months. Step 2: Convert months to years by dividing by 12. Repayment period in years = 42 months12 months/year Repayment period in years = 3.5 years The total repayment period is 3.5 years. 1.1.2 Determine the total repayment cost, in rands, for this item. Step 1: Identify the monthly instalment and the number of months. Monthly instalment = R1 078.26 Number of months = 42 Step 2: Calculate the total repayment cost. Total repayment cost = Monthly instalment × Number of months Total repayment cost = R1\,078.26 × 42 Total repayment cost = R45\,286.92 The total repayment cost is R45 286.92. 1.1.3 The advertised price for this item is R29 999.00. Furn-Furnitures offers a 17% discount for once-off cash payments. Calculate the amount the buyer will finally pay. Step 1: Identify the advertised price and the discount percentage. Advertised price = R29 999.00 Discount = 17% Step 2: Calculate the discount amount. Discount amount = 17\% of R29\,999.00 Discount amount = 0.17 × R29\,999.00 Discount amount = R5\,099.83 Step 3: Calculate the final amount the buyer will pay after the discount. Final amount to pay = Advertised price - Discount amount Final amount to pay = R29\,999.00 - R5\,099.83 Final amount to pay = R24\,899.17 The buyer will finally pay R24 899.17. 1.2 On the same set of axes, project this information comparing the tariffs of these providers. Label your graph adequately. To compare the tariffs, you will plot the cost of a call (in Rands) against the duration of the call (in minutes). Let t be the duration of the call in minutes and C be the cost of the call in Rands. • Off-net calls: FreeCom Off-net: Charges R1.20 per minute. C_FreeCom Off-net(t) = 1.20t Talkcom Off-net: Charges 79 cents (R0.79) per minute. C_Talkcom Off-net(t) = 0.79t • On-net calls (for both networks): On-net calls are billed for the first 3 minutes, with a cap of R3.60 for calls shorter than 60 minutes. This means the rate for the first 3 minutes is R1.20 per minute (R3.60 / 3 minutes), and then the cost remains R3.60 for calls longer than 3 minutes but shorter than 60 minutes. On-net (Both FreeCom and Talkcom): C_On-net(t) = 1.20t & if 0 < t 3 \\ 3.60 & if 3 < t < 60 Graphing Instructions: 1. Draw a set of axes. Label the horizontal axis "Call Duration (minutes)" and the vertical axis "Cost (Rands)". 2. Plot the line for FreeCom Off-net: This is a straight line starting from (0,0) with a gradient of 1.20. For example, at t=10 minutes, C = R12.00. 3. Plot the line for Talkcom Off-net: This is a straight line starting from (0,0) with a gradient of 0.79. This line will be less steep than FreeCom's off-net line. For example, at t=10 minutes, C = R7.90. 4. Plot the tariff for On-net calls: For 0 < t 3 minutes, draw a straight line from (0,0) with a gradient of 1.20, reaching the point (3, R3.60). For 3 < t < 60 minutes, draw a horizontal line from (3, R3.60) to (60, R3.60). 5. Label each line clearly on the graph (e.g., "FreeCom Off-net", "Talkcom Off-net", "On-net Calls"). What's next?
