PAR A cell phone company offers the following plans: A) Monthly charge (which includes 3000 "anytime" minutes): $30, and the charge for additional minutes is $0.05 (5 cents) per minute. B) Monthly charge (which includes 3000 "anytime" minutes): $25, and the charge for additional minutes is $0.25 (25 cents) per minute. 1) Write an equation to represent the relationship between the monthly cell phone charge and the number of minutes used, for each plan (so you'll have two equations). Let y represen the total cell phone charge and x represent the total number of minutes. 2) Xina talks for 1800 minutes one month. What will her charge be for each plan? Clearly indicate the charge under each plan. Which plan would be a better choice if Xina were to talk for 1800 minute each month? 3) Jacob talks for 4000 minutes one month. What will his charge be for each plan? Clearly indicate the charge under each plan. Which plan would be a better choice if Jacob were to talk for 4000 minutes each month? 4) Benjamin has a cell phone and plan B above. He lets his daughter Sonia borrow the phone for one entire month and she talks 6000 minutes. How much will Ben be charged? How much would he have saved IF he had plan A instead
