an article with a net weight of 10 lb (pounds) is packaged in a box that weighs 1/2 lb. If 20 of these boxed articles are put into a freight container 15 lb, what is the gross weight?

Respuesta :

the article is 10 lbs...so 20 of them = (10 * 20) = 200 lbs
the box is 1/2 lb....so 20 of them = (1/2 * 20) = 10 lbs
the freight container is 15 lbs

for a total of : 200 + 10 + 15 = 225 lbs <==
