You have been transported back in time, and you can save an ancient ancestor from being hanged on Gallows Hill. All that you have to do is to pay her jail bill. (In 1692, people were billed for their jail expenses.) Her bill is itemized below, but you'll have to do some math to save her. She was imprisoned from January 25 until April 4, 1692.
The colonists are still using the British currency system, and unfortunately the British are not yet on the decimal system. There are twelve pence to a British pound. Furthermore, you only have modern American money with you, so you will have to make a conversion. Each British pound is worth five modern American dollars.
To save your ancestor, you'll have to figure out the bill in terms of modern American money. Are your math skills strong enough to save your ancestor, or will your family's genetic history be permanently altered?
How much money will it cost you to save your ancestor ?
(CAUTION: Look up the "Gregorian Calendar" to see when it was adopted and to determine if 1692 was a leap-year.)
