Let's put a specific value in for

and then expand what we discover into a more general statement of the situation.

Assume for the moment that the amount of money spent on the fruit was $9.00. Clearly you can see that each of the nine pounds must have cost $1.00. Likewise, if the store clerk had asked for $18.00, each pound would have been worth $2.00, and if the bill had been $27.00 -- I would put the pears back and investigate the price of apples.

The pattern seems to be that if I divide the total cost,

in dollars, by the number of pounds of fruit purchased, the result is the cost in dollars per pound.

dollars per pound.

for this situation.
