The original value of the items can be called as "x", from that we can calculate the first disccount, which is shown below:
[tex]\text{discount}=0.4\cdot x[/tex]This is because we need to remove 60 % from the original value, x. After that there was an additional discount of 20%, therefore we have:
[tex]\begin{gathered} \text{ final price}=0.8\cdot(0.4)\cdot x \\ \text{ final price}=0.32\cdot x \end{gathered}[/tex]The final price is 32% of the original one.
