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

Describe at least three effects of the drug war in Mexico.
Vlada [557]
We show that municipalities that are exogenously exposed to the Drug War experience a 40% decrease in export growth on the intensive margin. Large exporters suffer larger effects, along with exports of more complex, capital intensive, and skill intensive products. Finally, using firm level data, we provide evidence consistent with violence increasing marginal exporting costs.
