Question

You are getting new phone for your birthday there is a $50 activation fee due when you get the phone you then you will be paying $99 each month write an equation in slope intercept form that gives the total cost of the phone

Answer 1

Equation for total cost will be
`y= 99x+55`

Explanation:

Given: Activation fees= $50

Due per month to be paid= $99

Now, finding the total of the phone.

Total cost=
`Activation\ fees+ (due\ to\ be\ paid\ each\ month* number\ of\ months)`

Lets assume the number of months, due to be paid be "x" and total cost be "y".

∴ Slope will be
`99`, which is due paid every month and
`constant\ value\ 50\ will\ be\ intercept`

∴ Forming an equation on the total cost of phone.

⇒
`y= 99x+55`

Hence, the equation for the total cost of phone will be
`y= 99x+55`
