Question

A local gym charges a $25 monthly membership fee plus $2 per hour for aerobics classes. What is the linear equation that describes the relationship between the total monthly cost (Y) and the number of class hours each month (X)

Answer 1

The equation is same as the equation for a straight line

Y= mx+c

Explanation:

The linear equation that describes the relationship between the total monthly cost Y and number of class hours in each month X is the same as the equation of line which is

`Y= mx+c\\\\ Y= 2X+25`

where Y= the dependent variable, monthly cost

x= the independent variable, the number of hours for aerobic classes

c= the intercept, $25
