Step-by-step explanation:

First you take the starting value and multiply it by 0.15 or 15%. Then you need to subtract that value from starting value. Then you get your final answer.

300 pounds of oranges were purchased at $0.24 per pound. The desired markup is 50% based on selling price, but 21% spoilage is e
andrezito [222]
1. The problem indicates that 300 pounds of oranges were purchased at $0.24 per pound, so the cost is:
 
 300x$0.24=$72
 
 2. A percent of 21% spoilage is expected, which means that 89% of 300 pounds of oranges left, is:
 
 300x0.89=267 pounds of oranges
 
 3. We want to calculate the selling price per pound of 267 pounds of oranges, so let's call this value "x":
 
 Markup %=(Markup/cost)x100
 
 Markup=267x-72
  
 4. The desired markup, based on selling price, is 50%. So, when we substitute the values, we obtain:
 
 (267x-72/72)x100=50
 
 5. Let's clear the "x":
 
 (26700x-7200/72)=50
 26700x-7200=50x72
 26700x-7200=3600
 26700x=3600+7200
 x=10800/26700
 x=$0.40
 x=40 cents
 
 What should the selling price per pound be?
 
 The answer is: 40 cents or $0.40

Which modified box plot represents the data set? <br><br>10,12,2,4,24,2,7,7,9
Gelneren [198K]

Answer with explanation:

The Data Set is→ 10,12,2,4,24,2,7,7,9

Arranging the data in ascending order

2,2,4, 7,7,9,10, 12, 24

Number of observation is odd,

So, Median

\frac{9+1}{2}=5^{th} Observation

5th Observation = 7

Q_{1}

=First Quartile  of data set that is from first variate to Median value

={2,2,4,7,7}

So, Q_{1}=4

Q_{3}

=Third Quartile of data set that is from last variate to Median value

={7,9,10,12,24}

So, Q_{3}=10

Minimum value in data set = 2

Maximum value in data set = 24

Plotting the Box plot

Option C , is correct Box plot.
