Answer:
a) $86.11
b) $467.33
Step-by-step explanation:
no. of gallons saved 'n' per year
n = (10000/33) - (10000/36)
n = 2500/99
Amount saved = 3.41×n = 3.41×2500/99
= $86.11
b) over 5 years:
86.11( 1 + (1.041) + (1.041)² + (1.041)³ + (1.041)⁴ )
= 86.11(5.427157431)
= $467.33
Equation of the line in slope intercept form is
y = 1/4 * x + 5. Slope is 1/4. Intercept is 5.
If x= 4, y = (1/4)*4 + 5 = 6.
The point (4,6) lies on the line.
Equation of the line in point slope form is
(y - y1)= m * (x - x1) where m is slope & (x1,y1) is point on the line.
Substituting slope m= 1/4 & point (4,6),
Equation of the line in point-slope form is:
(y - 6) = 1/4 * (x - 4).

Answer:
Step-by-step explanation:
If the temperature at 1:00 is x, then Jonestown's temperature at 3:00 is
x-10-8 (since it dropped 10 degrees then 8 more degrees)=x-18
Using x for Cooperville too, we get x-6-2 (since it drops 6 degrees then 2 more degrees) = x-8
Since -8 is greater than -18, Cooperville's temperature is warmer and Jonestown's temperature is lower aka colder<span />
