    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

    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
