Question

A bookstore ships books that weigh 24 oz each in cartons that weigh 8 oz each. Which expression gives the weight of a carton containing n books?

a. 8n + 24
b. 24n + 8
c. 24(n + 8)
d. 32n

Answer 1

a) 8n+24
the weight of the carton stays the same, but each book weighs 8 oz, so you'd have to multiply each book by 8 oz to get the weight.
