An apartment complex has a storage tank to hold its heating oil. The tank was filled on January 1, but no more deliveries of oil will be made until sometime in March. Let t denote the number of days after January 1, and let y denote the number of gallons of fuel oil in the tank. Current records show that y and t will be related by the equation y = 30,000 - 400t.
(a) Graph the equation y = 30,000 - 400t.
(b) How much oil will be in the tank on February 1?
(c) How much oil will be in the tank on February 15?
(d) Determine the y-intercept of the graph. Explain its significance.
(e) Determine the t-intercept of the graph. Explain its significance.
