Chris has a cell phone with a flat monthly fee of $50 for unlimited calls. He pays $0.25 for each text message. Write a function that describes the total cost for one month.

y = .25x + 50

Step-by-step explanation:

Let's use the slope-intercept equation for this problem:

y = mx + b

where m is the slope and b is the y-intercept

In this problem, m is the amount Chris pays per text and b is the flat rate.

m = price per text = .25

b = flat monthly fee = 50

Let's plug these values into the equation:

y = mx + b

y = .25x + 50

where y is the total cost for a month and x is the number of text messages

Therefore, the function is y = .25x + 50
