5. There are 24 gloves in a dozen PAIRS, so multiply 30*24.
6. Learn the formula for converting Celsius to Fahrenheit.
7. The gross weight is the weight of the package plus the contents. They give you the gross weight and the package weight, so subtract to find the contents weight. (Ever notice that boxes of food have "Net Weight" listed at the bottom? That's the weight of the food, not the whole package.)

1 dozen = 12 articles.
30 dozens = 12 × 30 = 360 pairs gloves. = 360 × 2 = 720 (option B)
F = 9C/5 +32
= 9×40 /5 +32
= 72 + 32 = 104 degree F (option D)
1 pound = 16 oz
Net content = Total wt. – Packing wt.
= 11p 5 oz – 1 p 15 oz
pound ounce
11 ----- 5 you can not subtract 15 from 5 so add 16 to 5 and subtract 1 from 11
– 1 ---- 15
So it is 10 pounds 21 ounces – 1 pound 15 ounces.
= 9 pound 6 ounces. (option C)
