Markup. In this exercise, we introduce the concept of markup. The markup on an item is the difference between how much a store sells an item for and how much the store paid for the item. Suppose Wegmans (a northeastern U.S. grocery chain) buys cereal at \(\$ 1.50\) per box and sells the cereal for \(\$ 2.29\).

a. Determine the markup in dollars.

b. The markup is what percent of the original cost? Round the percentage to one decimal place.
