Residential solar panels can convert up to 18 percent of the sunshine that falls on them into electricity. How would you write an inequality that shows the possible range of electricity (f) produced by a given amount of sunshine?
Let s be the amount of sunshine falling on the solar panels (measured in percentage), and f be the amount of electricity produced by the solar panels.
Since solar panels can convert up to 18 percent of the sunshine into electricity, we can write the inequality as:
0 ≤ f ≤ 0.18s
This inequality shows that the amount of electricity produced (f) is between 0 and 18 percent of the amount of sunshine falling on the panels (s).
