Shawn belongs to a book rental club. His mother gave him a $45 gift card for the club as a birthday present. The club charges members $2.00 to rent e-books and $3.50 for print books. Use a constraint equation to find out how many of each type of book Shawn can rent with his $45 gift card. Find two possible combinations of rentals that would serve as solutions to the equation. Write a general description of other combinations based on the constraint equation.

- Write a constraint equation for the relationship described.
- Use the constraint equation to determine two possible combinations of rentals, then interpret the solutions in the context of the problem.
- Describe other combinations based on the constraint equation.
