The surface of Grand Lake is at an elevation of 648 ft. During the current drought, the water level is dropping at a rate of 3 inches per day. If this trend continues, write an equation that gives the elevation in feet of the surface of Grand Lake after \( x \) days.
Answer (2)
The equation representing the elevation of Grand Lake after x number of days, given a decrease of 3 inches per day, is Elevation = 648 - 0.25x, where 0.25 is the daily loss rate in feet and x represents the number of days. ;
The equation representing the elevation of Grand Lake after x days is Elevation = 648 − 0.25 x , where 0.25 feet is the rate at which the elevation decreases per day. This equation shows how the lake level changes over time due to the ongoing drought conditions. For every day that passes, the elevation decreases by 0.25 feet.
