The selling price s(c)after a 45% markup of an item as a function of the stores' cost c.


The total number of miles m(r)covered when you walk 7 miles before lunch, and you walk for 2 hours at r mi/hr after lunch.

How many ounces are in a pound? 16. So you multiply the number of ounces (z) by 16 to get the pounds. Therefore,

p(z) = 16z


The selling price (s) is the original cost (c) plus 45%. That is 1.45 * cost, or 1.45c. Therefore,

s(c) = 1.45c
