Answer:
The correct answer is fixed costs.
Explanation:
Fixed costs are the cost that is spent on fixed inputs. They do not vary with the level of output. For instance insurance, rent, etc. They do not change with the change in the quantity of product, unlike variable costs.
The variable costs are the cost incurred on variable inputs. They vary with the level of output produced.
Explanation:
A. When microchip used in smartphones become less costly to produce, the supply of smartphones are going to increase, causing a fall in equilibrium price and a rise in equilibrium quantity.
since one of the resources used to make smartphones has become cheaper, more smartphones would be produced, raising its supply, increased supply causes fall in price and rise in equilibrium quantity.
B. since the ALS bucket challenge went viral, supply and demand for research would increase, causing equilibrium price or opportunity cost to either rise or remain unchanged. the equilibrium quantity will then rise, fall or remain unchanged
Answer:
She invested $2,167
Explanation:
As interest rate is not compounded, the 9-month interest of a 8% annual interest is simply:
8% * 9 / 12 = 6%
Let A be the amount of money she invest. After 9 month she will receive:
A * 0.06 dollars.
And the actual amount is $130. So she invested
A = $130 / 0.06 = $2,167
