Answer: The total of $350,000 will be Maria and Javier's qualified business income.
Explanation:
The amount of guranteed payments, i.e., $500,000 will not be included in the qualified business income. Therefore, their qualified business income is $350,000. Since they are equal partners, we will divide the $350,000 by 2 which will give us $175,000 for each of them.
