Simba travel agency arranges trips for climbing mount kilimanjaro. for each trip, they charge an initial fee of \$100$100 in addition to a constant fee for each vertical meter climbed. for instance, the price for climbing to the shira volcanic cone, which is 30003000 meters above the base of the mountain, is \$400$400. let f(d)f(d) denote the fee of a trip ff (measured in dollars) as a function of the vertical distance climbed dd (measured in meters). write the function's formula.

The required function formula is,  

Step-by-step explanation:

Here, For each trip, they charge an initial fee of $100 in addition to a constant fee for each vertical meter climbed.

And, d represents vertical distance climbed, and f(d) represents total fee.

Thus function which represents the total fee is,

f(d)= 100+k d, where k is any constant.

According to the question, For instance, the price for climbing to the Shira Volcanic Cone, which is 3000 meters above the base of the mountain, is $400.

Therefore, f(3000) = 400= 100+3000k

300= 3000k ⇒ k=1/10

thus, required function is, f(d)= 100+1/10 d,

Where d is the distance traveled vertically.

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
