To solve the problem, we need to use the provided ratio of earnings between Brayden and Dominic and the total amount of money they earned.
The ratio of Brayden's earnings to Dominic's earnings is 3:1. This means that for every 3 parts that Brayden earns, Dominic earns 1 part.
Let’s denote Brayden's earnings as 3x and Dominic's earnings as 1x.
The total earnings can be expressed as: \[ 3x + 1x = 48 \]
This simplifies to: \[ 4x = 48 \]
Now, divide both sides by 4 to find x: \[ x = 48 / 4 \] \[ x = 12 \]
Now, we can determine Dominic's earnings, which is represented by 1x: \[ 1x = 1(12) = 12 \]
Therefore, Dominic earned $12.
So the answer is: $12
