6. Value after 1 year = 22.75 + 650 = £672.75 Total interest = 722.75 – 650 = £72.75 Back to Home Question 1 • 3.5% of 650 = 0.035 x 650 = 22.75 • In 2001, John deposits £650 in the bank at an interest rate of 3.5%. • How much is his deposit worth after 1 year? • In 2002, the interest rate changed to 3.2%, and in 2003 it changed again to 4.1%. Calculate how much interest John will have earned at the end of 2003. OR 650 x 1.035 = £672.75 (b) 3.2% of 672.75 = 0.032 x 672.75 = 21.53 Value at end of 2002 = 672.75 + 21.53 = £694.28 4.1% of 694.28 = 0.041 x 694.28 = 28.47 Value at end of 2003 = 694.28 + 28.47 = £722.75 Begin Solution Continue Solution OR 672.75 x 1.032 x 1.041 = 722.74 Markers Comments Total Interest = 722.74 – 650 = £72.74 Calculations using PercentagesMenu

7. State calculation for percentage Clearly add interest and original amount Value after 1 year = 22.75 + 650 = £672.75 Interpret interest percentage Use the answer from part (a) Substitute correct value Clearly calculate total interest Total interest = 722.75 – 650 = £72.75 Back to Home Marker’s Comments • 3.5% of 650 = 0.035 x 650 = 22.75 OR 650 x 1.035 = £672.75 (b) 3.2% of 672.75 = 0.032 x 672.75 = 21.53 Value at end of 2002 = 672.75 + 21.53 = £694.28 4.1% of 694.28 = 0.041 x 694.28 = 28.47 Value at end of 2003 = 694.28 + 28.47 = £722.75 Next Comment OR 672.75 x 1.032 x 1.041 = 722.74 Calculations using PercentagesMenu Total Interest = 722.74 – 650 = £72.74
