Then the current sum of their ages is 15 + 60 = 75. You must add 40 to 75 to get to 115. Since 2 is added to the sum of their ages every year, it will take 20 years to increase the sum of their ages by 40.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "John \n" ); document.write( " \n" ); document.write( "My calculator said it, I believe it, that settles it \n" ); document.write( " ![]() \n" ); document.write( " |
