Learning objects School canteen: restock: level 2

TLF ID L1931

Buy supplies online for a school canteen. Purchase given amounts of items such as muffins or bread rolls. Notice that the unit price of the items remains the same regardless of the quantity purchased. In this level, perform slightly harder calculations to work out how many packs you will need. For example, in order to purchase 156 bread rolls (available in packs of 12), how many packs will you need to buy? Or, to purchase 72 fruit bars (available in packs of 24), how many packs will you need to buy? Calculate total costs. Complete the shopping list and calculate the total cost. This learning object is the second in a series of eight objects that progressively increase in difficulty.
