Reasoning A store sells packages of comic books with a poster. A poster and 7 comics cost $15.99. A poster and 16 comics cost $24.99. Write a linear function rule that models the cost y of a
package containing any number x of comic books.
Suppose another store sells a similar package, modeled by a linear function rule with initial value
$8.50. Use pencil and paper. Explain which store has the better deal.
The linear function rule is y=0.
