Answer: $162
Explanation:
Here's the remainder of the question:
What is the amount paid to an employee that works 6 hours and sells 3 wagons?
Since the expression given is:
= 12h + 30w
where h = 6 hours
w = 3 wagons
12h + 30w
= 12(6) + 30(3)
= 72 + 90
= 162
The amount paid to the employee will be $162
