Answer: option C is the correct answer.
Explanation:
The natural gas company charges a $17.01 connection fee plus $1.88 per 8 cubic feet of gas used.
If a family uses 96 cubic feet of gas, their original bill would be
17.01 + (1.88 × 96)/8
= 17.01 + 22.56 = $39.57
In the winter peak usage months, November through February, they charge each customer a peak usage surcharge of $27.43.
Therefore, the amount by which their bill would increased because of the peak usage surcharge is
39.57 + 27.43 = $67
