Evan has a cell phone plan that cost $30 per month and $0.25 per minute of phone use . let y represent the monthly cost of cell phone service after x minutes of phone use

The equation is y= 30 + 0.25x

Step-by-step explanation:

So y is your monthly cost. 30 is the constant because it is always a 30 dollar charge per month. Now it is 0.25 per minute so you need a variable, I like to use x but you can use anything. So we have y = 30 + 0.25x

Hopefully this helped you!
