how would i solve that @neonumbrella5115

OpenStudy (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

Maybe you made a mistake because the answer is 48.

OpenStudy (neonumbrella5115):

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|
