document.write( ": A thief steals a number of rare plants from a nursery. On the way out, the thief meets three security guards, one after another. To each security guard, the thief is forced to give one-half the plants that he still has, plus 2 more. Finally, the thief leaves the nursery with 1 lone palm. How many plants were originally stolen? I did this one, but I am not sure if it was done correctly. My answer is 76. Sometimes I think I over think the problem.

Algebra.Com's Answer #106543 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! A thief steals a number of rare plants from a nursery. On the way out, the thief meets three security guards, one after another. To each security guard, the thief is forced to give one-half the plants that he still has, plus 2 more. Finally, the thief leaves the nursery with 1 lone palm. How many plants were originally stolen? I did this one, but I am not sure if it was done correctly. My answer is 76. Sometimes I think I over think the problem. \n" ); document.write( ": \n" ); document.write( "Let x = no. of plants stolen \n" ); document.write( ": \n" ); document.write( "After the 1st guard: \n" ); document.write( "x - (.5x+2) \n" ); document.write( "x -.5x - 2 \n" ); document.write( ".5x-2 plants left \n" ); document.write( ": \n" ); document.write( "After the 2nd guard \n" ); document.write( "(.5x-2) - (.5(.5x-2)+2) \n" ); document.write( ".5x - 2 - (.25x-1+2) \n" ); document.write( ".5x - 2 - (.25x+1) \n" ); document.write( ".5x - 2 - .25x - 1 \n" ); document.write( ".25x - 3 plants left \n" ); document.write( ": \n" ); document.write( "After the 3rd guard \n" ); document.write( "(.25x-3) - (.5(.25x-3)+2) = 1 \n" ); document.write( ".25x - 3 - (.125x-1.5+2) = 1 \n" ); document.write( ".25x - 3 -(.125x+.5) = 1 \n" ); document.write( ".25x - 3 -.125x -.5 = 1 \n" ); document.write( ".125x - 3.5 = 1 \n" ); document.write( ".125x = 1 + 3.5 \n" ); document.write( "x = \n" ); document.write( "x = 36 plants \n" ); document.write( ": \n" ); document.write( "Check solution \n" ); document.write( "36 - 20 = 16 \n" ); document.write( "16 - 10 = 6 \n" ); document.write( "6 - 5 = 1 \n" ); document.write( " |
