Answer:
28 ways
Step-by-step explanation:
After placing 1 ball in each of the seven bins, there are two balls left.
If we place both balls in a single bin, there are 7 different ways to place the balls (place both on bins 1 through 7).
If we place each of the remaining balls in a different bin, the number of ways to place the balls is:

The total number of ways to distribute those balls is 21 + 7 = 28 ways.
The bill was $132
42% was for gas.
Multiply the total bill by 42% ( 0.42) to find the amount spent on gas:
132 x 0.42 = $55.44 was spent on gas.
Now subtract that amount from the total to find how much was spent on electricity:
132 - 55.44 = $76.56 was spent on electricity.
