The Water Company Has A Different Monthly Pricing Plan For Residential Customers Than For Business Customers class=

Sagot :

SOLUTION

From the graph giving in the question, we just trace the point on the graph and locate the value on the y-axis

Considering the image below

Form the Image above

When the Monthly water usage is 22 HCF, tracing the yellow line we can see that

[tex]\begin{gathered} \text{Business plan cost \$36} \\ \\ \text{ Residential plan cost \$44} \end{gathered}[/tex]

Therefore the residential plan cost more

The residential plan cost more by

[tex]\begin{gathered} \text{ \$44-\$36} \\ =\text{ \$8} \end{gathered}[/tex]

Part B

Both monthly plans cost the same when the amount of the monthly water usage is

14 HCF

Since the line of the business plan is above the Residential plan before the line intercept, i.e between 2 HCF to 12HCF.

The business plan will cost more
