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

If she has $33, how much do they have together?

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.
