Question

A 7th-grade class is going on a class trip to an amusement park. The total cost for each student is $49. Included in that price is a $7 admission fee to the park and 3 ferris wheel passes. Which equation is set up and solved correctly to determine the cost of 1 ferris wheel pass (f)?

Answer 1

To determine the cost of one ferris wheel pass, you can set up and solve the equation $49 = $7 + 3f.

Step-by-step explanation:

To determine the cost of 1 ferris wheel pass (f), we can set up the equation:

Total cost = $49 = $7 (admission fee) + 3f (cost of 3 ferris wheel passes)

Solving for f, we can isolate the variable by subtracting the admission fee from the total cost and then dividing both sides of the equation by 3:

49 - 7 = 3f

42 = 3f

Dividing both sides by 3:

42/3 = f

f = 14
