Answer: The total profit is $129
Step-by-step explanation:
The total revenue, was $147 (the total they earned), and the cost of the materials is $18 (how much they returned for the materials)
The total profit is computed as the difference between the revenue and the costs, then the total profit of the kids in this case is:
Profit = $147 - $18 = $129
This means that Tia and Jaden earned $129, if they divide it evenly, each one of them gets $129/2 = $64.5
