Suppose the price of a DVD rose from $15 to $17 and the quantity demanded decreased from 1,000 per month to 900 per month. Us

Andrews [41]

Answer:

Using the midpoint formula, the 12.5 percent change in price lead to a 10.5 percent change in the quantity demanded.

Step-by-step explanation:

This problem is related to the price elasticity of demand.

The price elasticity of demand is defined as the percent change in quantity demanded divided by the percent change in price.

Using the <u>midpoint formula</u>:

The formula for percent change in quantity demanded is:

Percent change in quantity demanded $=\frac{Q_{2}-Q_{1}}{\frac{(Q_{1}+Q_{2})}{2}} \times 100$

The formula for percent change in price is:

Percent change in price $=\frac{P_{2}-P_{1}}{\frac{(P_{1}+P_{2})}{2}} \times 100$

Given:

$Q_{1} = 1000\\Q_{2}=900\\P_{1}=\$15\\P_{2}=\$17$

Percent change in quantity demanded =

$=\frac{900-1000}{\frac{(900+1000)}{2}} \times 100\\=-10.53\%$

Percent change in price =

$=\frac{17-15}{\frac{(17+15)}{2}} \times 100\\=12.5\%$

The complete statement is:

Using the midpoint formula, the 12.5 percent change in price lead to a 10.5 percent change in the quantity demanded.

A bike shop sells you a bicycle for $63 and a helmet for $21. The total cost is 150% of what the shop spent originally. How much

marshall27 [118]

The bike shop made $28 dollars profit. First, you add the cost of the bike and the cost of the helmet, which is $84. Then you divide that by 150 to get what 1% would be, which is .56. Then you multiply that by 50%, which is the part of the price that the shop profited, which is $28.
