Since it is 25% all you would have to do is mutiply it by 4 to get 160. So in conclusion 160 is the answer.
.08 x .04 is the right answer
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.
