Answer:

  • 5-piso: 21
  • 1-piso: 31

Step-by-step explanation:

Let x represent the number of higher-value coins. Then the total value is ...

  5x +1(52 -x) = 136

  4x +52 = 136 . . . . . . . . simplify

  4x = 84 . . . . . . . . . . . subtract 52

  x = 21 . . . . . . . . . . divide by 4

Carlo has 21 5-piso coins, and 31 1-piso coins.
