School canteen: estimate and check: level 2
TLF ID L1934
Buy supplies online for a school canteen. Purchase given amounts of items such as bottles of orange juice and sesame bars. Notice that unit prices vary depending on the multiples in which items are sold. Look at the shopping list and check the prices and package sizes from the price catalogues of two traders. Estimate which trader will supply all the goods for the lowest total cost. In this level, perform slightly harder calculations to test your estimate of the total cost from each price catalogue. This learning object is the last in a series of eight objects that progressively increase in difficulty.
