    Solving a linear equation we can conclude that Ricardo’s allowance was $55.50

    How to find Ricardo’s allowance?

    Let’s define x as Ricardo’s allowance.
    We know that Ricardo spent half of his allowance, then at this point, he has x/2 left. Now he spends $5.25 in a snack, and after that, he has a total of $22.50 left.
    Then we can solve the linear equation:
    x/2 – $5.25 = $22.50
    x/2 = $22.50 + $5.25 = $27.75
    x = 2*( $27.75) = $55.50
    Then we can conclude that Ricardo’s allowance was $55.50
