Brayden and Dominic earned money in a ratio of 3:1. If the total amount they earned is $48, we can set up the following equation:
3x + 1x = $48
Combining like terms, we get:
4x = $48
Dividing both sides of the equation by 4, we find:
x = $12
Since Dominic's earnings are represented by 1x, or $12, Dominic earned $12.
Therefore, the correct answer is $12.
