# School canteen: restock: level 1

TLF ID L1927

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. Perform basic calculations to work out how many packs you will need. For example, in order to purchase 80 bread rolls (available in packs of 10), how many packs will you need to buy? Or, to purchase 60 fruit bars (available in packs of 12), 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 first in a series of eight objects that progressively increase in difficulty.
