Suppose that a cell phone monthly rate plan costs the user 5 cents per minute beyond a fixed monthly fee of $20. This implies that the relationship between monthly cost and monthly number of minutes is linear.

y = 20 + .5x

Step-by-step explanation:

Suppose that a cell phone monthly rate plan costs the user 5 cents per minute beyond a fixed monthly fee of $20. This implies that the relationship between monthly cost and monthly number of minutes is linear. Write an equation that relates total monthly cost to monthly minutes used.

Fixed monthly fee = $20

Fee per minute = $0.5

Number of minutes = x

Variable monthly cost = 0.5x

Let Total monthly cost = y

Total monthly cost = fixed monthly cost + variable monthly cost

y = 20 + .5x

Equation that relates total monthly cost to monthly minutes used is y = 20 + .5x

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!
