A quart of milk and cream contains 28 ounces of milk. If 8 ounces of cream are added, what percent of the new mixture is cream?

Divide.

8/28 = ?

Multiply the decimal answer by 100 to get the percentage.

the new mix of 32+8=40 oz contains 4+8=12 oz of cream

12/40 = 30%

To find the percentage of cream in the new mixture, we need to calculate the total weight of the new mixture and then find what portion of that weight is cream.

1. Start with the initial weight of milk and cream, which is 28 ounces.

2. Add the weight of cream that is added, which is 8 ounces.

Total weight of the new mixture = 28 ounces + 8 ounces = 36 ounces

3. Now, we need to find the portion or percentage of cream in the new mixture.

Percentage of cream = (Weight of cream / Total weight of the new mixture) x 100%

= (8 ounces / 36 ounces) x 100%

≈ 22.22%

Therefore, approximately 22.22% of the new mixture is cream.

To find the percentage of the new mixture that is cream, we need to determine the total weight of the mixture and the weight of the cream.

Given that a quart of milk and cream contains 28 ounces of milk, we can find the weight of the mixture by converting the quart to ounces. Since a quart is equal to 32 ounces, the weight of the mixture is 32 ounces.

Now we can determine the weight of the cream. Initially, the mixture contains 28 ounces of milk, so the rest of the 32-ounce mixture must be cream. Therefore, the weight of the cream is 32 - 28 = 4 ounces.

After adding 8 ounces of cream, the new weight of the cream is 4 + 8 = 12 ounces.

To find the percentage of the new mixture that is cream, we can calculate the ratio of the weight of the cream to the total weight of the mixture and multiply by 100.

Percentage of cream = (12 / 32) × 100 ≈ 37.5%

Therefore, approximately 37.5% of the new mixture is cream.
