We let y equal to the elevation above sea level so that the elevation of the rock climber after x minutes of climbing would be:
y = 2x + 50
His initial height can be calculated when x is equal to zero it is when the climber is not yet climbing. Therefore, the rock climber'sinitial height above sea level would be 50 meters.
Answer:
(B)
Step-by-step explanation:
(A)The given equation is:

Substituting the value of x=20, we get



(B) The given equation is:

Substituting the value of x=20, we get


(C) The given equation is:

Substituting the value of x=20, we get


(D) The given equation is:

Substituting the value of x=20, we get


Thus, the equation
results in the highest earning y.
