      So you fill in the function of putting in "k" where there's an 'x' and instead of labelling y =, you instead label it as k = because in the question it says, "in terms of k"

      i remember doing that question last year in the exam and that question took me as long to do as the rest of the paper. i advise to go onto the 2015 marking scheme as theyll break down the question. i think the answer was something like 42000

      the question im talking about is "Dermott calculates that after tax has been deducted his investment will be worth 5223.60 at the end of the second year. Calculate the rate of interest for the second year." the rate of interest for the 1st year is 3% and the second year will have a bigger one, tax of 41% will be deducted from the interest
