Question

A music-streaming service charges $9 per month for a single user. Additional users within the same household can be added for $3 per month. Write an equation that shows how the monthly cost, y, depends on the number of additional users in the household, X. Do not include dollar signs in the equation. y=​

Answer 1

The equation that shows the monthly cost is y = 9 + 3x

What is the equation that represents the monthly cost?

The monthly cost is a function of the charge for a single user and the cost of additional users. The monthly cost increases with the number of additional users.

The charge for a single user can be considered a fixed cost since it remains constant while the cost of the additional user can be considered a variable cost since it increases with the number of users.

Y = 9 + 3x
