Answer:
See step by step solution below
Explanation:
Given that; y = 245.82 + 1.13x
If x = 65°C
y= 245.82 + 1.13(65)
y= 319 pounds of steam
Given that for the first month;
y1= 245.82 + 1.13x
For the second month
y2 = 245.82 + 1.13(x - 5)
y1 - y2 = ∆y
∆y = 245.82 + 1.13x - [245.82 + 1.13(x - 5)]
∆y = 5.65
