An airline finds that if it prices a cross-country ticket at $200, it will sell 300 tickets per day. It estimates that each $20 price reduction will result in 50 more tickets sold per day. Find the ticket price (and the number of tickets sold) that will
maximize the airline's revenue.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
