Low-energy light bulbs also save money in the long run.
<h3>Mathematical operations</h3>
Cost of 1 low-energy bulb = 400 P
Cost of 1 filament buld = 50 P
Cost of electricity for 1 hour for low-energy bulbs = 0.2 p
Cost of electricity for 1 hour for filament bulb = 1.0 p
Total cost of electricity for 10,000 hours for low-energy bulb:
10,000 x 0.2 p = 2,000 p
Total cost of electricity for 10,000 hours for filament bulb:
10,000 x 1.0 = 10,000 p
Total cost of low-energy bulb + electricity = 2,000 + 400
= 2,400 p
Total cost of filament bulb + electricity = 10,000 + 50
= 10, 050 p
Thus, low-energy bulbs may have an initial higher cost, but they save a significant amount of money in the long run.
