Algebra.Com's Answer #810464 by greenestamps(13200)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "The statement of the problem is faulty. Age problems should have whole number answers; this one does not. \n" ); document.write( "There is also a problem with the statement that the father is \"3 times older than\" his son. That is a phrase that is almost always used incorrectly to mean that if the son's age is x then the father's age is 3x. \n" ); document.write( "But \"3 times older than his son\" means the son's age, x, PLUS \"3 times more\" his son's age (3x), making \"3 times older than x\" equal to x+3x=4x. \n" ); document.write( "Note that is similar to an increase of 300% in a number making the number 4 times as big as it was previously. The original 100% of the number, plus the increase of 300%, makes a total that is 400% of the original number. \n" ); document.write( "The statement of a math problem should NEVER use the phrase \" 3 times older than\" or \"5 times larger than\", because the intended meaning is almost never the correct meaning. \n" ); document.write( "This problem is especially badly created, in that the solutions are not whole numbers with EITHER interpretation of the given information.... \n" ); document.write( " \n" ); document.write( " |
