Answer:
payback period is 9.4785 ≅ 9.5 years
Explanation:
BTU stands for British thermal units and MCF stands for the volume of 1,000 cubic feet.
We know that one thousand cubic feet (Mcf) of natural gas equals 1.037 million Btu.
Difference between heat loss before and after installation = (42-28) millions BTU = 14 millions BTU
14 million BTU is equivalent to --
1.037 million BTU = 1 MCF
1 million BTU = (1/1.037) MCF
14 million BTU = (1/1.037) x 14 MCF = 13.5004 MCF
Cost of 13.5004 MCF = = $8.94 x 13.5004 = $120.6935
Pay back period = (1144/120.6935) = 9.4785
Therefore, her payback period is 9.4785 ≅ 9.5 years
The result of the isolation of the Australian continent for millions of years was because the continent has no fossil record of species evolution.
The supercontinent Pangaea was believed to exist in early times and incorporated all the landmasses on Earth
- The theory of continental drift explains that plate whichs forms the lithosphere of continent continue to move and has been in process for million of years ago
- The theory of continental drift does applies to Australia continent as well because it is believed the continent moves away and isolates from the supercontinent Pangaea
Hence, the Option A is correct because the result of the isolation of the Australian continent for millions of years was because the continent has no fossil record of species evolution.
