Problema Solution
Lake Travis, at 679.6 feet above seal level, is 99% full. It is expected to rise between 682 and 685 feet. Would Lake Travis become 100% full if it reached 685 fee?
Answer provided by our tutors
let 'h' represent the level of the lake when it is 100% full
we will assume that the volume of the lake is directly proportional to its level
679.6 : 0.99 = h : 1.00
by solving we find
h = 686.46 ft

since 685 < 686.46 we conclude that the lake will not be 100% full when it reaches 685 feet.
