Buy supplies online for a school canteen. Purchase given amounts of items such as bottles of orange juice and boxes of sultanas. Notice that the unit prices are different for packs of different sizes. Perform basic calculations to work out how many packs you will need, and which available pack size will be the cheapest. For example, in order to purchase 144 boxes of sultanas (available in packs of 6 for $2.40, packs of 18 for $6.75 or packs of 36 for $13.80), how many packs will you need and which will be the cheapest option? Complete the shopping list and calculate the total cost. This learning object is the third in a series of eight objects that progressively increase in difficulty.
