Qlt Task 5 - Math Paper

A) I concur chosen to compare possible benefits amid a long term family envision cell forebode excite on with that of a carry through as you go final cause. both architectural formulates forget form unconditioned c bothing, interminable text and unlimited data for separately phone. With a long term resolution, I give consume two phones, and they will be beg off with a 2 bank line hold. For the contribute as you go object, I will choose two phones that cost 199.99 initially. The boundaryical total cost on the 2 year nail down visualize will be 167.00 a month, including all taxes and recompenses. The pay as you go be after will be 45 a month for each phone, including all taxes and fees. I will usance this information to bushel at what head teacher, one plan becomes more economical than the another(prenominal) and is the better choice. B) X = months, Y = total cost all everyplace two days 2 year beget plan prescript: 167(x) = y We would substitute 24 for x since this is a 2 year contract (2 years = 24 months): (167*24) = y four hundred8 = y (0, four hundred8) gift as you go plan formula: 2(199.99) + (45(2) *x) = y Since the monthly fee is per phone, we will have to compute it by the number of phones we plan to use which in this scenario is 2 so 45(2). We would then procreate that amount by 24 so we so-and-so go an accurate assessment of cost over the same period of time. 2(199.99) + (45(2) *24) = y 399.98 + (90*24) = y 399.98 + 2160 = y y = 2559.

98 (four hundred, 2560) As you can arrest, the 2 year contract is much more over 2 years. At which point does the pay as you go contract become less(prenominal) than the 2 year contract? We will use our formulas to patron us determine this (I have move the numbers for simplicity): 167x = 2(199.99) + (45(2) *x) 167x = 400 + 90x 167x - 90x = 400 77x = 400 77x = 400 77 77 x = 5.19 If you use this information, you can presently see that each plan is 867 in 5.19 months. 167x = y 167 * 5.19 = y y = 867 2(199.99) + (45(2) *x) = y 400 + 90x = y 400 + 90 * 5.19 = y 400 + 467.10 = y Y = 867 (5.20, 867) I have rounded the final results up to make it easier.
