Jake pack 12 jars of paint in a box. Each jar and its contents weighed 10 ounces. The empty box weighs 1 pound 14 ounces. What is the total weight of the pact box?

Respuesta :

The weight of 12 jars is 12 times the weight of one jar. The weight of jars and box together is the sum of those weights.

... 12 × (10 oz) + 1 lb + 14 oz = 1 lb + 134 oz

... = 1 lb + 8 × (16 oz) + 6 oz . . . . . . 1 lb = 16 oz

... = 9 lb 6 oz
