190 + 890 + 780 + 690 + 590 + 490 + 390 + 290 + 190 + 90 = (190 + 890) + (780 + 690) + (590 + 490) + (390 + 290) + (190 + 90) = 1080 + 1470 + 1080 + 680 + 280 = 4590 Answer = 4590
The answer = 4560
The result of the equation - 100 plus 90 plus 60 plus 80, is found as follows; 100 + 90 + 60 + 80 = ( 100 + 90 ) + 60 + 80 = 190 + ( 60 + 80 ) = 190 + 140 = 330 Answer = 330
The answer = 4560
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?
17 plus 190 = 17 + 190 = 207.
190 + 890 + 780 + 690 + 590 + 490 + 390 + 290 + 190 + 90 = (190 + 890) + (780 + 690) + (590 + 490) + (390 + 290) + (190 + 90) = 1080 + 1470 + 1080 + 680 + 280 = 4590 Answer = 4590
