Full solution

Q. Esmerelda bought a bag of jelly beans. There were 2424 green jelly beans, which made up 8% 8 \% of all the jelly beans in the bag. How many jelly beans were in the bag?
  1. Understanding the relationship: Understand the relationship between the part, whole, and percentage.\newlineThe problem states that 2424 green jelly beans make up 8%8\% of the total jelly beans. We can use the percent formula: Part=Percent (as a decimal)×Whole\text{Part} = \text{Percent (as a decimal)} \times \text{Whole}.\newlineHere, the Part\text{Part} is the number of green jelly beans (2424), and the Percent (as a decimal)\text{Percent (as a decimal)} is 8%8\% or 0.080.08. We need to find the Whole\text{Whole}, which is the total number of jelly beans.
  2. Setting up the equation: Set up the equation to find the total number of jelly beans.\newlineUsing the percent formula, we have:\newline24=0.08×Whole24 = 0.08 \times \text{Whole}\newlineLet's denote the Whole (total number of jelly beans) as 'WW'.\newlineSo, the equation becomes:\newline24=0.08×W24 = 0.08 \times W
  3. Solving for 'W': Solve for 'W' by isolating it on one side of the equation.\newlineTo find 'W', we divide both sides of the equation by 0.080.08:\newlineW=240.08W = \frac{24}{0.08}
  4. Performing the division: Perform the division to find the total number of jelly beans.\newlineW=240.08W = \frac{24}{0.08}\newlineW=300W = 300
  5. Verifying the solution: Verify that the solution makes sense.\newlineIf there are 300300 jelly beans in total and 2424 are green, then the green jelly beans should indeed make up 8%8\% of the total. To check:\newlinePercentage of green jelly beans =(Number of green jelly beansTotal number of jelly beans)×100= \left(\frac{\text{Number of green jelly beans}}{\text{Total number of jelly beans}}\right) \times 100\newlinePercentage of green jelly beans =(24300)×100= \left(\frac{24}{300}\right) \times 100\newlinePercentage of green jelly beans =8%= 8\%\newlineThis confirms that our solution is correct.
