Question

A gym charges $60 per month plus $5 per visit. A linear model is written where "x" is the number of visits per month and "y" is the total cost of the gym. What would be the slope of the model? A:65 B:5 C:60 D:55

Answer 1

We want to create a linear model where "x" is the number of visits per month and "y" is the total cost of the gym so then the equation needs to be given by:

`y = 5x +60`

And for this case the slope would:

`m =5`

And the best answer would be:

B:5

Explanation:

For this case we know that a gym charges $60 per month plus $5 per visit. So then the fixed cost is 60 and the variable cost per visit is 5 .

We want to create a linear model where "x" is the number of visits per month and "y" is the total cost of the gym so then the equation needs to be given by:

`y = 5x +60`

And for this case the slope would:

`m =5`

And the best answer would be:

B:5
