Question

Your total monthly bill (T

) from the Electric and Gas Company depends on how much electricity and how much gas you use each month. For every kilowatt hour of electricity (k
) you use, you are charged $0.25
and for each therm (t
) of gas used you are charged $0.97
.

Which of the following equations represents the relationship between electricity and gas used and your bill?

Answer 1

• Answer:

The equation representing the relationship between Electricity and Gas used, and your Bill is:

T = 0.25 * k + 0.97 * t

• Explanation:

Make a plan:

We need to find the equation that represents the relationship between the total monthly bill (T), The Kilowatt Hours of Electricity used (k), and the Terms of Gas used (t).

T = 0.25 * k + 0.97 * t

• Solve the problem:

1 - Write the Equation for the cost of Electricity:

0.25 * k

2 - Write the Equation for the Cost of Gas:

0.97 * t

3 - Combine the Equations to Represent the total Monthly Bill (T):

T = 0.25 * k + 0.97 * t

• Draw the Conclusion:

Hence, The equation representing the relationship between Electricity and Gas used, and your Bill is:

T = 0.25 * k + 0.97 * t

I hope that helps!
