Ismael is comparing cell phone plans before upgrading his phone. Ameri-Mobile offers a low activation fee, but a high monthly payment. Cell-U-Later offers a lower monthly rate, but the activation fee is higher. Create a possible algebraic expression for both Ameri-Mobile and Cell-U-Later that shows the amount paid after an unknown amount of months have passed. Justify how you created those expressions, and identify what each term and factor represents in terms of the cell phone plans.

OK.......let the montly cost of Cell-U-Later be M...   and let the montly cost of  Ameri-Mobile be (M + q)  where q is some positive quantiy.

Next, let the activation fee  for Ameri-Mobile be A... and let the activation fee for Cell-U-Later be (A + r)  where, again, r is some positive quantity.

So the total cost of Ameri-Mobile after some months is given by:

A + (M + q)n      where n is the number of elapsed months

And the total cost of Cell-U-Later after some months is given by:

(A + r) + Mn      where, again, n is the number of elapsed months

 

P.S.  ........Ismael should avoid Captain Ahab at all costs.....I hear he's kind of cranky these days after his last run-in with Moby D**k.......
