A seasoning blend is 4% onion powder, by mass. How much pure onion powder should they include in a 72g bottle to make the final blend have 20% onion powder? ◻ g

Identify Concentration: We need to find the amount of pure onion powder to add to reach 20% concentration in a 72g bottle.Define Variable: Let x be the amount of pure onion powder to add.Calculate Remaining Amount: The rest of the bottle will be filled with the original 4% onion powder blend, which will be 72g - x.Total Mass of Onion Powder: The total mass of onion powder in the new blend will be x (from the pure onion powder) plus 0.04(72 - x) (from the 4% blend).Set Up Equation: We want the total mass of onion powder to be 20% of the total mass of the blend, which is 72g. So, we set up the equation: x + 0.04(72 - x) = 0.20 * 72.Solve Equation: Solving the equation: x + 2.88 - 0.04x = 14.4.Combine Like Terms: Combine like terms: x - 0.04x = 14.4 - 2.88.Divide to Solve: 0.96x = 11.52.Calculate Final Value: Divide both sides by 0.96 to solve for x: x = 11.52 / 0.96.Calculate the value of x: x = 12.

Q. A seasoning blend is

4\%

onion powder, by mass.

\newline

How much pure onion powder should they include in a

72\,\text{g}

bottle to make the final blend have

20\%

onion powder?

\newline

\square\,\text{g}

Identify Concentration: We need to find the amount of pure onion powder to add to reach $20\%$ concentration in a $72g$ bottle.
Define Variable: Let $x$ be the amount of pure onion powder to add.
Calculate Remaining Amount: The rest of the bottle will be filled with the original $4\%$ onion powder blend, which will be $72g - x$ .
Total Mass of Onion Powder: The total mass of onion powder in the new blend will be $x$ (from the pure onion powder) plus $0.04(72 - x)$ (from the $4\%$ blend).
Set Up Equation: We want the total mass of onion powder to be $20\%$ of the total mass of the blend, which is $72g$ . So, we set up the equation: $x + 0.04(72 - x) = 0.20 \times 72$ .
Solve Equation: Solving the equation: $x + 2.88 - 0.04x = 14.4$ .
Combine Like Terms: Combine like terms: $x - 0.04x = 14.4 - 2.88$ .
Divide to Solve: $0.96x = 11.52$ .
Calculate Final Value: Divide both sides by $0.96$ to solve for $x$ : $x = \frac{11.52}{0.96}$ .
Calculate Final Value: Divide both sides by $0.96$ to solve for $x$ : $x = \frac{11.52}{0.96}$ .Calculate the value of $x$ : $x = 12$ .
