Artemon [7]

Answer:

The correct answer is letter "A": affordable food creates an external benefit rather than an external cost in the case.

Explanation:

Externalities are costs third parties have to be responsible for even if they were not involved in causing the externality. There are positive externalities and negative externalities. Positive externalities are those that third parties benefit from. Negative externalities affect third parties.

Thus, importing less-expensive but chemically-dangerous food will create a positive externality to consumers purchasing those types of foods since less money is getting out of their pockets without them having to influence discounts.

Answer: An astute trader can make $ 41,666.66.

Explanation: You must first change

$ 1,000,000 per pounds, which would leave a total of £ 500,000. ($ 1,000,000 / 2.00 = £ 500,000;).

Secondly spend £ 500,000 to euros, obtaining € 600,000 (£ 500,000 x 1.20 = € 600,000;).

Thirdly, with euros, buying dollars again, obtaining $ 960,000 (€ 600,000 x 1.60 = $ 960,000), that is, an arbitrage loss of -40,000 in relation to the initial investment.

Finally you must return in the opposite direction:

$ 1,000,000 / 1.6 (€) / 1.2 (£) * 2 - $ 1,000,000 = $ 41,666.66 that is, an arbitrage profit.

Nico is saving money for his college education. He invests some money at 99%, and $17001700 less than that amount at 4 %.4%. T

Rufina [12.5K]

Answer:

Nico invest $2500 at 9% interest rate and $800 at 4% interest rate.

Explanation:

He invests some money at 9%, and $1700 less than that amount at 4 %.

Let Nico invest $x at 9%.

It means he invest $( x-1700) at 4%.

The investments produced a total of $257 interest in 1 yr.

$x\times \frac{9}{100}+(x-1700)\times \frac{4}{100}=257$

$0.09x+(x-1700)0.04=257$

$0.09x+0.04x-68=257$

$0.13x-68=257$

Add 68 on both sides.

$0.13x=257+68$

$0.13x=325$

Divide both sides by 0.13.

$x=2500$

Nico invest $2500 at 9% interest rate.

$x-1700=2500-1700=800$

Nico invest $800 at 4% interest rate.

Therefore Nico invest $2500 at 9% interest rate and $800 at 4% interest rate.
