Correct answer is D the cost of natural gas is $0.83 per unit.

Answer:

The correct option is D. The cost of natural gas is $0.83 per unit.

Step-by-step explanation:

Consider the provided equation.

[tex]116y = 96.28[/tex]

We need to solve the above equation for y.

Divide both the sides by 116.

[tex]\frac{116y}{116} = \frac{96.28}{116}[/tex]

[tex]y=0.83[/tex]

Now consider the provided options.

Hence, the correct option is D. The cost of natural gas is $0.83 per unit.
