3. From the bellow information, calculate a cost effective decision for a designer.
A designer needs six 300 mm x 300 mm x 0.5 mm sheets of aluminium, which cost £5.00 each.
The designer also has the option of buying a larger sheet of material and cutting it down to the size
they need. The larger sheet is a 900 mm x 600 mm x 0.5 mm sheet and costs £28.00.
How much of a saving, in both pounds (£) and percentage (%), could you make by getting the larger
sheet?
