Final answer:
The correct equation to determine the cost of 1 Ferris wheel pass is F = (49 - 7) / 3.
Step-by-step explanation:
The correct equation to determine the cost of 1 Ferris wheel pass (F) is option A: F = (49 - 7) / 3.
To find the cost of 1 Ferris wheel pass, we subtract the admission fee from the total cost and divide the result by the number of Ferris wheel passes. In this case, the admission fee is $7 and the total cost is $49, so we subtract $7 from $49 to get $42. Then, we divide $42 by 3 (the number of Ferris wheel passes) to get $14, which is the cost of 1 Ferris wheel pass.
