1 ton= 2000 pounds
STEP 1:
Convert each car's weight to pounds:
= 2000 pounds + 1400 pounds
= 3400 pounds per car
STEP 2:
multiply each car's weight in pounds by the total number of cars
= 3400 pounds * 6 cars
= 20,400 pounds total
ANSWER: The truck is transporting 20,400 pounds.
Hope this helps! :)
