Just multiply 190 by 1.12 and you will have your answer. This is how I get the "1.12". The final amount will be 190 dollars PLUS twelve percent of 190 dollars. This can be expressed: 190 dollars (1 PLUS 12 percent). 190 ( 1 + .12). The 190 times 1 gives you, not surprisingly, the whole original 190 dollars. The 190 times .12 gives you the twelve percent. So 190 X 1.12 is a simple calculation that will give you the answer. We don't normally think that multiplying something by one could ever be the least bit useful, but it is useful. What mathematical property does this solution illustrate?
