1."You know the bags we bought last week?", asked Ben, looking at an invoice. "Two styles and as many of each as its price in pounds. The difference between the totals is just £136." "Yes I did notice," Sarah replied. "Well the funny thing is that last month we had a smaller invoice for two entirely different styles of bags. Again the quantity of each style was equal to the price in pounds, and there was exactly that same £136 difference." How many were bought on the two occasions?

41 and 42 bags, 19 and 22 previous month

33 and 35 bags, 15 and 19 previous month

37 and 44 bags, 9 and 11 previous month
