Question

Denise's monthly cell phone plan is $29.95 plus $0.10 per minute.

Answer 1

1) Since we've been told that Denise's monthly cell plan has a steady cost

of $ 29.95 plus $0.10 per minute

Let's call the number of minutes 'x'

And we can write a function for that:

C (x) = 0.10x +29.95

C(x) = Cost per month (in dollars)

x = minutes
