The board of trustees for a school is considering a tuition increase. one faction in the board supports plan a, which involves raising the tuition 9% this year and 8% the next. others want plan b, which has the 8% raise this year and the 9% next year. some say it doesn't matter because in either case, the tuition is the same in the second year. does it make any difference as to which plan is implemented?

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.
