1. ### (a) Find a linear function C that models the cost of driving x miles per month.?

...4 + k ==> k = 380 - 120 = 260 verify: when y = 460, x = 800 so 460 = 800/4 + k ==> k = 460 - 200 = 260 So C(x) = (x/4) + 260 increase in cost per mile is 0.25 dollars

8. ### A plane cruising at 220 m/min starts its descent from 2.5 km at 150 m/min. Find the equation for its altitude "h" as a function of time "t".?

h = kt+c at t=0, h = 2500 m slope = k = –150 m/min h = –150t+c 2500 = –150•0 + c c = 2500 therefore equation is h = –150t + 2500 meters
