Jameis signed up for a cell phone plan that charges an initial monthly fee and a set rate per minute he talks on the phone each month. The equation he was given to calculate his total bill, y, was y = 0.25(x + 20) + 7 where x represents the number of minutes he talks on the phone in one month.

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.
