anonymous · Answer

I have no formula for it but I think he has 20 Php 5 peso coins :)

amistre64 · Answer

p @ 5 = (130 - 50(1))/(5-1) is my guess

amistre64 · Answer

what is a "php" ?

anonymous · Answer

Because 20*5= 100
Then he has 30 Php 1 coins
Then 30*1= 30

So 100+30= 130. :)

amistre64 · Answer

the long route is to set up a system of equations such that:

 a + b  =  t  ; fives + ones = 50

ax + by = z  ; x and y are the number of each and z = 130, now
                        eliminate to find your a and b

-ax -bx = -tx
  ax +by = z
--------------
   b(y-x) = z - tx

    b@y = (z-tx)/(y-x)

     p @ 5 = (130 - 50(1))/(5-1) = 20 pesos @ a 5 count

that needs an edit; x and y are the values for each coin; 5 and 1
