$0.07 When writing fractional amounts with a decimal point be VERY careful not to confuse the $ sign and the ¢ sign. It's common to find prices in stores that are written incorrectly, e.g. 0.50¢ when the amount is supposed to be 50 cents. Because a decimal point in a price indicates anything to the right of it is divided by 100, "0.50¢" isn't 50 cents, it's 50/100 of a cent - or half a penny!!
