Final answer:
The equation that is set up and solved correctly to determine the cost of 1 Ferris wheel pass (f) is 49 = 7 + 3f. To solve for f, subtract 7 from both sides and then divide by 3.
Step-by-step explanation:
The equation that is set up and solved correctly to determine the cost of 1 Ferris wheel pass (f) is option a) 49 = 7 + 3f.
To solve for f, we need to isolate it on one side of the equation. We can start by subtracting 7 from both sides of the equation: 49 - 7 = 7 + 3f - 7, which simplifies to 42 = 3f.
Next, we divide both sides of the equation by 3 to solve for f: 42 ÷ 3 = 3f ÷ 3. The left side simplifies to 14, and the right side simplifies to f. Therefore, the correct equation to determine the cost of 1 Ferris wheel pass is 14 = f.
