Titus works at a hotel. Part of his job is to keep the complimentary pitcher of water at least half full and always with ice. Wh
en he starts his shift, the water level shows 4 gallons, or 128 cups of water. As the shift progresses, he records the level of the water every 10 minutes. After 2 hours, he uses a regression calculator to compute an equation for the decrease in water. His equation is W –0.414t + 129.549, where t is the number of minutes and W is the level of water. According to the equation, after about how many minutes would the water level be less than or equal to 64 cups
<span>Let W= -0.414t + 129.549 be the given equation. For finding the value of t, we have to solve inequation and search for the unknown t value. That is as follow: -0.414t + 129.549</span>
