12h + 30w represents the amount paid to each employee.....where h is the number of hrs and w is the number of wagons sold.
working 6 hrs and selling 3 wagons.....so h = 6 and w = 3
12h + 30w = total pay
12(6) + 30(3) =
72 + 90 =
162 = total pay <===
I would think miles per hour would be the best units to use because that is what the speedometer of a car is read in. Hope this helped! comment back with any questions you still have!
Just add all the numbers together and then multiple it by 3
