    The ratio of Isabella’s money to Shane’s money is 3:11

    Isabella has $33.

    We can make a proportion to solve for how much money Shane has.

    A proportion is two ratios that are set equal to each other.

    Let’s call Shane’s money ‘S’

    We get this proportion: 3/11 = 33/x

    If we cross multiply we get:

    (33) * (11) = (3) * (x)

    Simplifying it, we get:

    363 = (3) * (x)

    Divide both sides by 3, we get:

    x = 121

    However, the question asks how much money they have together.

    Isabella + Shane = Total

    33 + 121 = $154

    They have $154 together.
