Josie spent 4/7 of the money in her purse on some books, and the rest of the money on 18 markers. Each marker cost $1.20. How much money was in Josie's purse to begin with ?

3/7 of total (call it t) on 18 markers
18 * 1.20 = 3 t/7 
we got 21.60 on the 18 markers but how do we get >> How much money was in Josie's purse to begin with ?

18 * 1.20 = 3 t/7
21.6 * 7 = 3t
151.2 / 3 = t
50.40= t
