Answer:
105
14
Explanation:
e(x) = 840 - 52.5x
To find e(14), just plug in 14 in for x.
e(14) = 840 - 52.5(14)
e(14) = 840 - 735
e(14) = 105
14 minutes after the cable car leaves the top of the hill, the elevation is 105 meters.
➷ Substitute in the value:
840 - 52.5(14) = 105
Since e(14) = 105, the elevation of the cable car would be 105 meters from the ground 14 minutes after it begins descending from the top of the hill
