A young boy stopped by the corner grocery store and read his list to the clerk:
โ10 pounds if sugar at 1.25 a pound; 4 pounds of coffee beans at 1.50 a pound; 2 pounds of butter at 1.10 a pound and 2 bars of soap at 83 pence each.
How much does that come to?โ
โTwenty-two pounds and thirty-six pence,โ replied the clerk.
โIf I gave you three ten pound notes, how much change would I get?โ
โSeven pounds and sixty-four pence.โ
With that the boy walked out saying:โThanks!
Thatโs my arithmetic homework done for tomorrow.โ
