Please answer question 6.5 with an explanation Thank you

Answer 1

Low-energy light bulbs also save money in the long run.

Mathematical operations

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.
