I am buying stationery for use in the office. I have 23 staff in the office and need to get 2 pens
and 1 notebook for each of them. The pens are sold in packets of either 10 or 12 and the
notebooks are sold in packets of 8 or 10. I decided to buy just the larger packets of each and
save any extra ones. I told my assistant how many packets of pens and notebooks to buy, but
when he returned I found that he had bought the smaller packets in each case. I am going to buy
sufficient extra pens and notebooks that I need for my staff singly. A single pen will cost 12¢ and
a single notebook will
