Joe bought a 2.08 * 10^4 pound tractor trailer to transport his world famous birthday cakes around the country. How many tons was the tractor trailer?

To determine the weight of the tractor trailer in tons, we need to convert pounds to tons.

First, let's recall that there are 2,000 pounds in a ton.

To convert pounds to tons, divide the weight in pounds by 2,000.

In this case, the weight of the tractor trailer is 2.08 * 10^4 pounds.

Dividing this weight by 2,000 gives us:

2.08 * 10^4 pounds / 2,000 = 10.4 tons

Therefore, the tractor trailer weighs 10.4 tons.
