Open Question: Help on this system of equations word problem? Desperately need help?
For each cell phone plan, write an equation that represents the total cost per month in terms of the number of additional minutes used. Don't forget to define your variables. - Verizon offers 700 minutes of calls per month for $45.99 with additional minutes costing 6 cents per minute. - Cingular offers 700 minutes for $29.99 per month with additional minutes costing 35 cents each. Solve the system of equations algebraically. Answer this question: No matter which plan you chose, there is a time at which Verizon's plan is a better deal. For how many total minutes of calls per month is Verizon's plan a better deal? Now answer this: A third company, Sprint, offers a plan that costs $49 for 500 minutes, and extra minutes are 2 cents each. Write an equation that represents the total cost per month in terms of the number additonal minutes used. (Remember what your variables stand for) For how many total minutes of calls per month is the Sprint plan the best deal of the three? If you give me valid answers and work I will give you 10 points.
