Question 917595: A carpet store charges a flat fee for installation of carpet that is priced by the square yard. Susan had 12 square yards of carpet installed for a cost of $400. The equation y � 400 = 25(x � 12) models the revenue of the carpet store, where x is the number of square yards purchased and y is the total cost to the customer. Which function models the cost of buying x square yards of carpet if the customer also pays for installation?

f(x) = 25x � 388
f(x) = 25x � 700
f(x) = 25x + 100
f(x) = 25x � 412
