Question

on a certain telephone rate plan, the price of a cellular telephone is $0.35 per minute or fraction thereof

Answer 1

Generate a function that can be used to calculate the cost

Answer 2

y=0.35x

When x, the number of minutes, increases, it is multiplied by the rate of $0.35 to generate the cost of the phone call.

For example, if my call lasted 10 minutes, I would have to pay 0.35*10 = $3.5
