Explanation / Answer

9)

a) f(t) = ( 2t + 5 ) / 7

f(7) = (2*7 + 5) / 7

f(7) = 19/7

b) f(t) = 4

4 = (2t+5)/7

28 = 2t + 5

23 = 2t

t = 23/2

10) cost of operating flight = $ 11500

each ticket costs = $ 123

so, profit function can be written as

P = 123n - 11500

11) f(100 ) = 1700

f(550) = 3900

we have two points

(100 , 1700) and (550, 3900 )

slope m = (3900 - 1700) / (550 - 100 ) = 44/9

y - 1700 = 44/9 (x - 100 )

f(x) = 44/9x + 10900/9
