The Ferris wheel in paradise park has w small seats and x large seats. Each small seat can hold y people and large seat can hold z people. How many people can ride the Ferris wheel on large seats?
There are a total of w + x = 3 + 7 = 10 seats on the Ferris wheel. Of those seats, w = 3 are small seats and x = 7 are large seats. Each small seat can hold y = 16 people and each large seat can hold z = 12 people. Therefore, the Ferris wheel can hold a maximum of w * y + x * z = 3 * 16 + 7 * 12 = 84 people on large seats.
