Each of the 18 tires of a fully loaded semi truck is bearing approximately 3,300 pounds. the unloaded truck and trailer, with the driver aboard weighs 30,000 pounds. the truck holds 26 pallets of cargo when it is fully loaded. what is the approximate average weight of one pallet of cargo? a. 1,131 lbs
b. 1,280 lbs
c. 1,633 lbs
d. 1,665 lbs

Process of elimination is helpful here. 

Starting with A, if every pallet weighs approximately 1,131 pounds and there are 26 pallets, then that's 29,406 total pounds of additional weight. Add that additional weight to the 30,000 of the truck and trailer and you have 59,406 total pounds. If you divide that number by 18, you get the total number of pounds that each tire is supporting. 59,406 divided by 18 is 3300, so that seems to be the answer. 

The correct answer is 10%
