A hotel has 80 rooms can rent all of them if the rental price per day is $300, but it has noticed that for each $6 of increase in the price, it would have an empty room. determine a. the rental price of the room in order to get a maximum income

b. amount of maximum income

c. the number of rooms that would be empty when the income is maximum.

46 dollars is the answer.

step-by-step explanation:

6*6 = 36,         36+10=46

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
