Kevin and Randy Muise are so popular personages that I devoted the entire lesson to them

    - Kevin and Randy Muise have a jar containing coins


Shortly speaking, you have this system of 2 equation

 N +   D =   65     (1)    (counting) coins)
5N + 25Q = 1225     (2)    (counting cents)


Or this single equation

4N + 25(65-N) = 1225.


Solve the system or the single equation, on your choice.
