So, first we have to get the potatoes to the same exact weight. So we divide the 12.5kg by 5 and then we get 2.5kg, which is the same as the supermarket potatoes. But then, since we divided the weight, now we have to divide the amount of euros by five, and then we get 1.80. So that means that at the farm shop, for every 2.5kg, you pay £1.80 for 2.5kg, which is £0.03 less that the supermarket potatoes.
