   Firstly 190$ is even so the number of 5$ is even and the number of 2$ is a multiple of 5.

   So 5k lots of 2$

   2n lots of 5$

   But if there are 4 less 5$ notes than 2$ notes

   5k – 4 = 2n

   Where 5k + 2n = 190$

   Or k * 10$ + n * 10$ = 190$

   Then k+n = 19

   Write n = 19 – k

   5k – 4 = 38 – 2k

   7k = 42

   k = 6

   n = 13

   So we have 130$ Of 5$ notes and 60$ of 2$ notew

   that’s 26 5$ notes and 30 2$ notes.
