Jerome has 30 coins consisting of Php 1 and 25 cents. The total money that he have is Php 12. What is the solution and answer?

Answer 1

Answer:

• Php 1: 6
• 25 cents: 24

Step-by-step explanation:

Let x represent the number of Php 1 coins Jerome has. Then his total value is ...

  0.25(30 -x) +1(x) = 12

  7.5 +0.75x = 12

  0.75x = 4.5 . . . . . subtract 7.5

  x = 6 . . . . . . . . . . divide by 0.75

Jerome has 6 Php 1 coins and 24 25 cent coins.
