There are two cell phone companies that offer different packages. Company A charges a monthly service fee of $32 plus $0.04/min talk-time. Company B charges a monthly service fee of $43 plus $0.03/min talk-time. Use a for your variable. The model for Company A can be written as A = The model for Company B can be written as B = If the average number of minutes used each month is 1,028, how much does this cost for each Company? Company A cost would be $ Company B cost would be $ Alvin wants to know what his average paddling rate was for a canoe trip to a campsite. On the way there it took him 8 hours against a river current of 4 km/ hr. On the way back, the same distance took him 6 hours with the same 4 km/hr current. Let r = Alvin's average paddling rate. Express the rates against the current and with the current in terms of r to complete the below table. Distance Against the current With the current d d Rate Alvin's average paddling rate was Time Using the information summarized in the above table, set up an equation to solve for Alvin's average paddling rate r. km/hour (If needed, round to 2 decimal places).
