A boutique prices merchandise by adding 80%. It later decreases by 25% the price of items that do not sell quickly. Does the ord

k0ka [10]

The order you apply the adjustments does make a difference because the percents that are applied will be applied to different amount.

For example, 80% of 100 = $80. The price would be $180.

Decreasing this by 25% 25% of 180 = $45; 180-45 = $135.

25% of 100 is not the same as 25% of 180.

Answer:

95.4% of family vehicles is between 1 and 3 years old.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 2

Standard Deviation, σ = 6 months = 0.5 year

We are given that the distribution of age of cars is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(family vehicles is between 1 and 3 years old)

$P(1 \leq x \leq 3)\\\\ = P(\displaystyle\frac{1 - 2}{0.5} \leq z \leq \displaystyle\frac{3-2}{0.5}) = P(-2 \leq z \leq 2)\\\\= P(z \leq 2) - P(z < -2)\\= 0.977 -0.023 = 0.954= 95.4\%$

$P(1 \leq x \leq 3) = 95.4%$

95.4% of family vehicles is between 1 and 3 years old.
