Question

Compact fluorescent light (CFL) bulbs reduce energy waste. The amount of energy

waste that is reduced each day in a certain community can be estimated by -b² + 8b
where b is the number of bulbs. Divide by b to find the average amount of energy
saved per CFL bulb.

Answer 1

The average amount of energy saved per CFL bulb can be found by dividing the energy waste reduction equation (-b^2 + 8b) by the number of bulbs (b).

So, the average energy saved per bulb (E) can be represented as follows:

E = (-b^2 + 8b) / b

To simplify, we can factor out the b term in the numerator:

E = (-b + 8)

So, the average energy saved per CFL bulb is equal to -b + 8.

It's important to note that this equation assumes a linear relationship between the number of bulbs and the energy saved, which may not necessarily hold true in reality. It's also important to take into account other factors that could affect the amount of energy saved, such as the usage patterns of the bulbs and the efficiency of the electrical system they are used in
