19 paddle boards were rented.

Step-by-step explanation:

Let x represent the number of surfboards that were rented.

Let y represent the number of paddleboards that were rented.

A total of 44 surfboards and paddleboards were rented. It means that

x + y = 44

For a two day rental at the surf shop, it cost $45 to rent a surfboard and $60 to rent a paddleboard.

The total cost of surfboards and paddleboards rented was $2265. This means that

45x + 60y = 2265 - - - - - - - - - 1

Substituting x = 44 - y into equation 1, it becomes

45(44 - y) + 60y = 2265

1980 - 45y + 60y = 2265

- 45y + 60y = 2265 - 1980

15y = 285

y = 285/15 = 19

x = 44 - y = 44 - 19

x = 25
