  30 ¢10 and ¢25 coins

  Step-by-step explanation:

  To find the number of coins:

  0.10 + 0.25 = 0.35

  ₱10.50 ÷ 0.35 = 30

  To check:

  30 × ¢25 = ₱7.50

  30 × ¢10 = ₱3.00

  ₱7.50 + ₱3 = ₱10.50

  There are 30

  Let x be the number of 10centavo and 25centavo(because they have the same number and that is why they also have the same variable to be used).

  0.10x + 0.25x = 10.50

  0.35x = 10.50

  Divide both sides by 0.35 in order to x to be alone.

  0.35x ÷ 0.35 = 10.50 ÷ 0.35

  x = 30
