Question

A climbing gym charges $50 a month but gives a permanent $5 discount for every person you refer to the gym. Let x be the number of people you’ve referred to the gym and y be your monthly cost, in dollars________

Answer 1

The equation that expresses the total cost in terms of the number of students in a class is y = 50 + 20x.

Step-by-step explanation:

The equation that expresses the total cost in terms of the number of students in a class is given by y = 50 + 20x, where y represents the total cost and x represents the number of students in the class.

The fixed cost of $50 per class is represented by the term 50, and the variable cost of $20 per student is represented by the term 20x.

For example, if there are 5 students in the class, the total cost would be y = 50 + 20(5) = 50 + 100 = $150.
