Respuesta :

We can model the problem as a linear equation in the slope-intercept form:

[tex]y=mx+b[/tex]

Where:

m = Slope = Cost per CD = 8.50

x = Number of CDs purchased

y = Total cost

b = y-intercept = Initial joining fee = 24

Therefore, the equation is:

[tex]y=8.50x+24.00[/tex]

If the cost per CD (m ) goes up by $1.00:

[tex]y=9.5x+24[/tex]
