Store A sells boxes of rice for $2.50 each. Store B sells rice by the pagind for $2.50 per pound.
The cost of an amount of rice at either store can be modeled by the function c(n) = 2.5
n, where n is the number of boxes for Store A and n is the number of pounds of rice
for Store B.
The domain of c(n) = 2.5n is all the real numbers.
For each store, drag the restriction needed on values of n for c(n) to model each
situation.
