Answer:

$60.00 /h

Step-by-step explanation:

y = mx + b

y, is the total charge

m, is the amount of money charged/h

x, is the number of hours

b, is the fixed rate

305 =m3 + 125

305-125 = m3

180/3 = m3/3

[60 = m]

Step-by-step explanation:

Please find the complete question in the attached file.

Throghout the question the calculated points are:

(0,0) , \ \ (40,252) \\(0,0) , \ \ (40,210) \\

Formula for Calculating slope:

M=\frac{y_2-y_1}{x_2-x_1}

For First point slope:

M=\frac{252-0}{40-0}=\frac{252}{40}= 6.3  \ \frac{people}{mi^2}

For second point slope: M=\frac{210-0}{40-0}=\frac{210}{40}=\frac{21}{4}= 5.25  \ \frac{people}{mi^2}
