Say you need $9,6$ml of plastic resin to mould a drum.

How many litres do you need to produce $50000$ drum? $[2]$

If one litre costs R $3000,$ then how many litres are needed to produce the $50000$ drums? $[1]$

If you had decided to round off the $9,6$ml to $10$ ml at the start of the calculation:

How many litres of resin would you need then? $[1]$
