Mary French uses gas to heat her home. She has accumulated the following information regarding her monthly gas bill and monthly

garik1379 [7]

Answer:

$Y=$24+0.09X$

Step-by-step explanation:

From the question we are told that

February Heat $H_1=1900\textdegree$

February Gas $G_1 =\$195$

April Heat $H_2=600\textdegree$

April Gas $G_2=\$78$

Generally equation for heating degree-days X is mathematically given by

$X=\frac{\triangle gas\ bills}{\triangle Heating\ days}$

$X=\frac{195-78}{1900-600}$

$X=\$ 0.09$

Generally the equation for gas bill Y is mathematically represented by

$Y=78-(600*0.09)\\Y=\$24$

The equation representing the relationship between the gas bill (Y) and heating degree-days (X) is

$Y=$24+0.09X$

5 / 22 = 4.4

Now lets check our work.

4.4 x 5 = 22
