Answer:
a. Plan I is better is we drive 300 miles in a day.
b. 150 miles.
Explanation:
a. if mileage is 300 then rental charges will be,
Plan I : $36 + 17 cents * miles
$36 + 0.17 * 300 = $41.10.
Plan II : $24 + 25 cents * miles
$24 + 0.25 * 300 = $99.00
Plan I total cost for 300 miles is $41.10 whereas Plan II total cost for 300 miles is $99.00. Plan I is better plan and cost effective.
b. For mileage (m) calculation we will use equation;
Plan I = Plan II
$36 + 0.17m = $24 +0.25m
0.25m - 0.17m = $36 - $24
m = $12 / 0.08
m = 150 miles.
Answer:
As with all probability sampling methods, simple random sampling allows the sampling error to be calculated and reduces selection bias. A specific advantage is that it is the most straightforward method of probability sampling.
Answer:
A.
Explanation:
Based on the information provided within the question it can be said that the most likely result would be the collapse of local fisheries, because of the damage to coral reefs from ocean acidification
. This is mainly because the coral reefs provide habitat for a vast majority of the fish, and the same carbon dioxide that is causing global warming is also causing ocean acidification. Which in term is destroying the coral reefs, and therefore the habitats of all these fishes who will die without them.
Answer:
The company's net operating income for May is $7,930
Explanation:
Sales revenue = $97,000
Variable costs
= $97,000 × (1 - 70%)
= $97,000 × 0.69
= $66,930
Fixed costs = $38,000
Therefore, net operating income = Sales - revenue - variable cost - fixed cost
= $97,000 - $66,930 - $38,000
= $7,930
Answer:
B
Explanation:
The Internal Rate of Return (IRR) is the profitability or the ability to generate revenues of the money that remains invested during the life of a proyect. It is also known as the discount rate or cost rate that makes the Net Present Value (NPV) equal to cero. When the NPV is greater than cero, then the proyect creates value ( it is attractive to investors) if it is less than cero, then the proyect destroys value and investors are going to loose money. If the NPV is equal to cero, then investors recover their investment but they do not obtain gains nor losses. The minimum rate of return is the one in which at least investors obtain the same amount ( in present value) of their investment; that is the internal rate of return (IRR).
