3 6. The marked price, inclusive of GST of a laptop is $3849.40 before a sale. During the sale, the laptop is offered at a 15% discount. The first 100 customers will be given an additional 10%off the discounted price. (a) Find the price of laptop excluding GST before the sale. [1] (b) Find the price paid by Jasper who is the 101st customer [2] (c) Find the price paid by Amber who is the 99th customer, giving your answer correct to the nearest cent. [2] 7. Danise received some money from her mother. He divides the money between shopping, education and savings in the ratio 4 : 7 : 5 respectively. (a) If he saved $2000, calculate the total amount of money he received from her mother. [1] (b) He invests all his savings into an investment plan that pays simple interest at a rate of 3% per annum for 5 years. Calculate the total amount that he will receive at the end of 5 years. [2] 8. On a particular day, the exchange rate between Australian dollars (A$) and Singapore dollars (S$) was S$1 = A$0.93. (a) Suzanne exchanged A$360 into Singapore dollars. Calculate how many Singapore dollars she received. Leave your answer correct to the nearest dollar. [1] (b) On the same day, the exchange rate between Singapore dollars and US dollars (US$) was US$1 = S$1.42. Michelle exchanged A$1400 into US dollars. Calculate how many US dollars she received.
