Answer:

47 therms

Explanation:

A $78.40 gas bill has a $22 monthly connection fee and charges of $1.20 per therm. You want to know the number of therms being charged.

Therms

Let t represent the number of therms at $1.20 each. The gas bill chargest are ...

1.20t +22 = 78.40

Solution

Subtracting 22 gives ...

1.20t = 56.40

Dividing by 1.20 tells the number of therms:

t = 56.40/1.20 = 47

The company used 47 therms.
