Carrots : Compare the following deals in a shop that sells carrots loose and in a packet : Packet: For 500 grams the cost is 70 pence. Loose: For 1 KG the price is £1.10 Use some basic maths to explain which is the cheaper price and why. Assume that the products are of equal quality and that the same quantity is to be purchased in each case.

My answer: Convert the packet into a form where it has a consistent weight with the loose weight per kilo: 500 grams is 70 pence. Therefore 1000 grams is 140 pence. Therefore 1KG is £1.40 Therefore the loose price of £1.10 per kilo is a cheaper price.

Cheese: One packet of cheese says that it is £6.00 for two 500 gram packets. Another says that it is £2.40 for 375 grams in just one packet. Which is the cheaper deal per kilogram assuming that use by dates are not an issue and that the two items are of the same quality?

My answer: Convert the 375 gram packet price into an amount per kilo. £2.40 / 0.375 = £6.40 You could also do £2.40 / 375 and then multiply by 1000 (first work out the price per gram and then multiply by 1000 to work out the price per kilo). The conclusion is that the £6.00 price for two 500 gram packets is the cheaper way of buying this product. [2 x 500g = 1000g]
