Answer:

$300

Step-by-step explanation:

So the equation would look like this since you pay a one time fee on $60 that is the y-intercept, and since you pay $40 per month that is you m or slope constant rate of change etc.

The equation looks like this.

y = 40x + 60

Since it wants to know how much after 6 months plug in 6 where the x is.

y = 40(6) + 60

y = 240 + 60

y = 300

$300

Hope this helps!!

Answer:

$420.00

Step-by-step explanation:

Let x = cost after 9 months. Let y = cost of phone.

x = y + (r · t)

y = $60.00

r = monthly rate of $40.00

t = time period of 9 months

x = $60.00 + [($40.00/month)(9 months)]

The months cancel, leaving dollars.

x = $60.00 + [$360.00] = $420.00
