(A) A man invests $5000 at 6% compound interest for 3 years. How much interest does he receive at the end of this period? (B) A car bought for $20 000 depreciates in value by 10% each year. (i) How much will the car be worth after 2 years? (ii) If after that time it is resold for $15 000 what is the percentage loss to the seller? Given that y is directly proportional to x and y = 54 when x=3, find (a) the value of the constant of proportionality. (b) the value of x when y=250. When a computer is sold for $2,752, the profit is 28%. Calculate the cost price of the computer. 10 Solve the equations: (i) 273-335 (ii) x=3+3=2x 2 (iii) x2-7x+12= 0 (A) A man invests $5000 at 6% compound interest for 3 years.
