Rudy worked hard all summer.Before school started,He decided to go shopping and spend some of his earnings.He spent one third of his money on a new shirt at Hot fashions in the mall.He then went to MArvins Music and bought a Cd with one third of the money he had left.AT movies-to go he spent one third of the money he now had on a video he wanted.He stopped one more time on his way home and bought a paperback at Berts book shop with one third of his remaining money.Rudy arrived home with just $16.00 in his wallet. How much money did he have when he started out?
Well, if 16 is one third of the money he spent at the Book shop. (d= the money Rudy spent at the book store) |dw:1423182800320:dw|
how would i solve that @neonumbrella5115
Well, first you need to isolate the variable. So, divide 16 by 1/3 or multiply 16 by 3.
16 divided by 1/3 equals 5.3
@mathmate
Maybe you made a mistake because the answer is 48.
Once you solve the amount of money he spent at the bookstore, then you can solve (using the same setup) how much he spent at the movie store. (m= money spent at movie store) |dw:1423183526566:dw|
