Answer:
Adriana made the most money
Explanation:
The total selling price of the unwanted items sold by both Mario and Adriana is given.
We can look for the greater figure, or better still find the positive difference between them to know which one is greater.
So, Selling price for Adriana = $294
And, Selling Price for Mario = $249
The difference in value is $294 - $249 = $45
So, Adriana made $45 more than Mario.
