Answer:
6% = 4500
5% = 3500
Explanation:
wo equations can be derived from the question
x + y = $8,000 equation 1
0.05x + 0.06y = $445. equation 2
x = amount invested in 5%
y = amount invested in 6%
multiply equation 1 by 0.05
0.05x + 0.05y = 400 equation 3
subtract equation 3 from 2
0.01y = 45
y = $4500
substitute for y in equation 1
8500 - 4500 = 3500
Answer:
the coefficient of elasticity is 1.25. therefore demand is elastic
Explanation:
Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.
Price elasticity of demand = percentage change in quantity demanded / percentage change in price
5% / 4% = 1.25
If the absolute value of price elasticity is greater than one, it means demand is elastic. Elastic demand means that quantity demanded is sensitive to price changes.
Demand is inelastic if a small change in price has little or no effect on quantity demanded. The absolute value of elasticity would be less than one
Demand is unit elastic if a small change in price has an equal and proportionate effect on quantity demanded
