Residential solar panels can convert up to 18% of the sunshine that falls on them into electricity. How would you write an air quality that shows the possible range of electricity (f) produced by given amount of sunshine?

f = k * s

where:
f = electricity produced by solar panels
k = efficiency of solar panels (0.18 for 18% efficiency)
s = amount of sunshine

Therefore, the equation can be written as:
0 ≤ f ≤ 0.18s

This equation shows that the electricity produced by solar panels ranges from 0% to 18% of the amount of sunshine that falls on them.

What’s the answer

The answer to the air-quality question is as follows:

f = k * s

where:
f = electricity produced by solar panels
k = efficiency of solar panels (0.18 for 18% efficiency)
s = amount of sunshine

Therefore, the equation can be written as:
0 ≤ f ≤ 0.18s

This equation shows that the electricity produced by solar panels ranges from 0% to 18% of the amount of sunshine that falls on them.
