Final answer:
To determine the number of hardcover books and paperbacks Turner can buy with $55, we can set up the equation 5x + 11y = 55, where x represents the number of hardcover books and y represents the number of paperbacks.
Step-by-step explanation:
To determine the number of hardcover books and paperbacks Turner can buy with $55, we can set up the following equation:
5x + 11y = 55
Where x represents the number of hardcover books and y represents the number of paperbacks. This equation states that the cost of the hardcover books (5x) plus the cost of the paperbacks (11y) should equal $55.
The equation is in standard form, which requires all variables to be on the left side and constants on the right side.
