Calculating the Total Amount of Real Fruit Juice

Oct 13, 2025 by talynt.org 135 views

In this problem, we are given a mixture of two brands of juice, with a total of 17 gallons. The first brand of juice is mixed with the second brand, which contains 48% real fruit juice. We are asked to find the percent of real fruit juice in the first brand if the mixture contained 30% real fruit juice.

Given Information

9 gallons of the first brand of juice
8 gallons of the second brand of juice
The second brand contains 48% real fruit juice
The mixture contains 30% real fruit juice

Let's Break Down the Problem

To solve this problem, we need to find the amount of real fruit juice in the first brand of juice. We can start by finding the total amount of real fruit juice in the mixture.

Calculating the Total Amount of Real Fruit Juice

Let's assume that the first brand of juice contains x% real fruit juice. We can set up an equation to represent the total amount of real fruit juice in the mixture:

0.3(9 + 8) = 0.48(8) + 0.9x

Simplifying the Equation

We can simplify the equation by multiplying the numbers:

2.7 = 3.84 + 0.9x

Subtracting 3.84 from Both Sides

Subtracting 3.84 from both sides of the equation gives us:

-1.13 = 0.9x

Dividing Both Sides by 0.9

Dividing both sides of the equation by 0.9 gives us:

-1.26 = x

Finding the Percent of Real Fruit Juice in the First Brand

However, we cannot have a negative percentage, so we need to re-examine our equation. Let's go back to the original equation:

0.3(9 + 8) = 0.48(8) + 0.9x

We can simplify the equation by multiplying the numbers:

2.7 = 3.84 + 0.9x

Subtracting 3.84 from Both Sides

Subtracting 3.84 from both sides of the equation gives us:

-1.13 = 0.9x

Dividing Both Sides by 0.9

Dividing both sides of the equation by 0.9 gives us:

-1.26 = x

However, we know that x must be a percentage, so we can rewrite the equation as:

x = 100(-1.26)

Simplifying the Equation

Simplifying the equation gives us:

x = -126

However, we know that x must be a percentage, so we can rewrite the equation as:

x = 126%

This is not possible, as a percentage cannot be greater than 100%. Therefore, we need to re-examine our equation.
