Ten pennies weigh an ounce. How much money is a ton of pennies?
Solution
There are 16 ounces in a pound and 2000 pounds in a ton. That's 32,000 ounces in a ton. At 10¢ per ounce, that's 320,000 pennies, or $3200.
Some say that we should quit using pennies and just round up or down to the nearest nickel. Does this result have a bearing on that discussion?
