Answer:
a) Gold = $1,380; Silver = $1,020
b) Gold = $1,300; Silver = $980
Explanation:
a) At first, with Qg = 60 and Qs = 270, the equilibrium prices for gold and silver are found by solving the following linear system:

Equilibrium price of gold is $1,380 and the price of silver is $1,020.
b) If the supply of gold increases to 120, since the goods are substitutes, there will be an increase in overall supply and the equilibrium price of gold and silver will decrease as follows:

Equilibrium price of gold is $1,300 and the price of silver is $980.
Answer:
$91 favorable
Explanation:
Variable overhead rate variance = (Standard variable overhead rate - Actual variable overhead rate) * Actual hour worked
Therefore, we have:
Variable overhead rate variance = ($8.00 - $7.90) * 910 = $91 favorable
Note: the variable overhead rate variance is said to be favorable becasue standard variable overhead rate is geater than the actual variable overhead rate.
Answer:
Limited natural resources such as infertile land and lack of coastal access can limit economic growth for a country.
Explanation:
Natural resources are a source of wealth for the country. Mineral such oil and precious stones have made nations wealthy.
Land is a factor of production. Lack of fertile lands will make a nation dependent on imports for its food security. Access to coastal areas facilitates cheaper and fast international trade. Landlocked countries use harbor of other nations for global business. Goods and services from landlocked counties may be more expensive as a result of high transport costs.
