1. A carton contains b boxes of paper plates, and each box contains n plates. If the carton costs c dollars, what is the cost per paper plate, in dollars, when the plates are bought by the carton?

Question

a. cbn
b. c/bn
c. bn/c
d. cn/b
e. n/cb

I do not know which. I got something like c=bn, but that is clearly not one of the choices.Help/explanation?

Answer 1

The cost of a carton according to problem = c
Total number of plates = bn
Thus the cost per plate is,
c / bn
