Here are the solutions for Question 8 and Question 9: Question 8: Vicky needs to calculate the total cost in Australian dollars and then convert that amount into Kina. Step 1: Calculate the total cost in Australian dollars. Total Cost (AUD) = Price of phone + Postage Total Cost (AUD) = \80 + \50 = \130 Step 2: Convert the total Australian dollars into Kina. The exchange rate is K1 = 0.3938 AUD. To find out how many Kina are needed for 130 AUD, divide the total AUD by the exchange rate. Kina needed = Total Cost (AUD)Exchange Rate (AUD per Kina) Kina needed = (130)/(0.3938) Kina needed ≈ 330.1168 Rounding to two decimal places for currency: Kina needed ≈ K330.12 Vicky will have to convert K330.12 into Australian dollars.
