Question 588737: A retailer wants to sell and make a profit of 30% of the cost of each item. The function s(c)=c+03c=1.3c, where c represents the cost of an item, can be used to determine the selling price. Find the selling price of an item that costs $11.50.

The item costs the merchant $11.50, so c=11.5.
The selling price, s, is calculated using the function s%28c%29=1.3c.
For c=11.5, s%2811.5%29=1.3%2A11.5=14.95.
The selling price is $14.95.
