Answer:
The amount paid to an employee was 162
Explanation:
The amount paid to an employee was given by the expression 12h + 30w.
Here, h represents the number of hours worked and w represents the number of wagons sold.
It is given that an employee works 6 hours and sells 3 wagons.
So, put h = 6 and w = 3, we get,
12h + 30w = 12(6) + 30(3)
= 72 + 90
= 162
Hence, the amount paid to an employee was 162.
