Brian can choose Plan A or Plan B for his long distance charges. For each plan, cost (in dollars) depends on minutes used (per month) as shown below.

(a)If Brian makes 160 minutes of long distance calls for the month, which plan costs more?
Plan A Plan B
How much more does it cost than the other plan?

(b)For what number of long distance minutes do the two plans cost the same?

If the time spent on long distance calls is less than this amount, which plan costs less?
Plan A Plan B

step-by-step explanation:

no oblique asymptote

step-by-step explanation:

to find the oblique asymptote of f(x)

here numerator has degree 1 and denomintor degree 2

degree of numerator < degree of denominator

hence there is no oblique asymptote

when the degree of the denominator > that of the numerator, we saw that the value in the denominator got so much bigger, so quickly,   giving us a horizontal asymptote of the x-axis. or we can write

f(x) = a polynomial of x + a proper fraction.

in this case only we have oblique asymptotes but not when numerator has less degree.

391.6 is the correct answer

i'm guessing it might be 40.
