A large glass of juice contains a mix of half mango juice and half pumpkin juice. A smaller glass contains pure pumpkin juice. If the two glasses are combined in a pitcher, the result will be 60% pumpkin juice. The volume of the small glass is 4 ounces; what is the volume of the large glass?

let the volume of the larger glass be x ounces

so volume in the pitcher
= x + 4

so .6(x+4) = 4 + .5x
.6x + 2.4 = 4 + .5x
.1x = 1.6
x = 16 ounces

To solve this problem, we can set up an equation based on the information given. Let's assume the volume of the large glass is x ounces.

According to the problem, the large glass contains a mix of half mango juice and half pumpkin juice. This means that the large glass has an equal amount of mango juice and pumpkin juice. Therefore, the large glass contains x/2 ounces of mango juice and x/2 ounces of pumpkin juice.

The small glass contains pure pumpkin juice, so it contains 4 ounces of pumpkin juice.

When the two glasses are combined in a pitcher, the result is 60% pumpkin juice. This means that the total volume of pumpkin juice in the pitcher is 60% of the total volume of the mixture.

Using this information, we can set up the equation:

(x/2 + 4) / (x + 4) = 0.6

Now, let's solve the equation:

Cross multiplying, we get:

(x/2 + 4) = 0.6(x + 4)

Distribute 0.6 to both terms in the parentheses:

x/2 + 4 = 0.6x + 2.4

Subtract 0.6x from both sides:

x/2 - 0.6x = 2.4 - 4

Combining like terms:

-0.1x = -1.6

Divide both sides by -0.1:

x = -1.6 / -0.1

x = 16

Therefore, the volume of the large glass is 16 ounces.
