Answer:
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
