Final answer:
The cost at the trampoline park for any number of people is C = 75 + 6n, where C is the total cost and n is the number of people.
Step-by-step explanation:
The expression that represents the cost for any number of people at the trampoline park is given by the equation C = 75 + 6n, where C is the total cost and n is the number of people. This equation includes a $75 reservation fee and a $6 cost per person. This is a linear equation, which is often used in situations where there is a fixed cost plus a variable cost dependent on the quantity.
For example, similarly, in Emma's Extreme Sports, the total cost Emma pays to hang-gliding instructors can be represented by the equation Total Cost = 50 + 20(number of students)
