Problema Solution
A purse contains 37 coins in P1 and P5 whose total value is P75. How many pieces of each kind are there?
Answer provided by our tutors
let
x = the number of P1 coins, x is non-negative integer
y = the number of P5 coins, y is non-negative integer
purse contains 37 coins
x + y = 37
total value is P75
1*x + 5*y = 75
by solving the system of equations
x + y = 37
x + 5*y = 75
we find
x = 27.5
y = 9.5
the solutions are not integers thus there is no solution for this problem
