Gross weight of the truck with 30 pigs = 8 tons, 1123 pounds and 6 ounces
= (8 × 2000 × 16) + (1123 × 16) + 6 ounces
= 256000 + 17968 + 6
= 273974 ounces
The average weight of one pig = 95 pounds 10 ounces
= (95 × 16) + 10 ounces
= 1520 + 10 = 1530 ounces
a. Net weight of the pigs in the truck = 30 × 1530 = 45900 ounces
= 2868 pounds 12 ounces
= 1 ton 868 pounds and 12 ounces
b. Weight of the empty truck = Gross weight of the truck containing 30 pigs - Net weight of the pigs in the truck
= 273974 - 45900
= 228074 ounces
= 14254 pounds 10 ounces
= 7 tons 254 pounds and 10 ounces
