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.
Add 68 on both sides.
Divide both sides by 0.13.
Nico invest $2500 at 9% interest rate.
Nico invest $800 at 4% interest rate.
Therefore Nico invest $2500 at 9% interest rate and $800 at 4% interest rate.
Answer:
coefficient = 0
Explanation:
We have the formula to calculate the price elasticity of demand as following:
<em>Elasticity coefficient = % Change in quantity/ % Change in price</em>
As given:
+) The percentage change in price is: (120-150)/150= - 20%
+) The quantity bought remains unchanged - which means the percentage change in quantity demanded is 0%
=> <em>Elasticity coefficient = % Change in quantity/ % Change in price</em>
<em>= 0/-20 = 0</em>
<em />
<em>So the coefficient of price elasticity of demand in this example would be 0</em>
