Question

A store sells packages of comic books With a poster. A poster and 3 comics cost 10.75 and a poster and 12 comics cost 19.75 write a Linear function tule that models the cost of y a package containing any number of x comic books. Suppose another store sells a similar package, modeled by a linear function rule with initial value at 5.75. Explain which store had the better deal

Answer 1

The linear function for the first store is y = 2.5x + 10.75, where x is the number of comic books and y is the cost of the package. The linear function for the second store is y = 2.5x + 5.75. The second store has the better deal, as the cost of the package is lower for any given number of comic books.
