Each tub of yogurt contains 1.85g of fat. The company would like to reduce this amount by 15%, but instead of changing the yogurt composition, the company would like to alter the serving size. How many fluid ounces will the new container be?

The new container will have 4.8 oz of yogurt.

Explanation:

Here, the given question is incomplete.

A local food company produces yogurt in ¾ = 0.75 cup tubs.

2 cups = 1 pint

2 pint = 1 quart

4 quartz = 1 gallon

15 fluid oz = 1 pint

Let us assume the needed quantity is m.

Here, the present weight of yogurt in the tub = 0.75 cup

So, 1 cup = 0.5 pint.

⇒ 0.75 cup = 0.5 x 0.75 = 0.375 pint

Also, 1 pint = 15 oz fluid

⇒ 0.375 pint = 15 x 0.375 = 5.625 oz

So, the current yogurt in the tub = 5.625 oz

Now, 1 oz = 28.3495 grams

⇒ 5.625 oz = 5.625 x 28.3495 = 159.4 ≈ 160 grams

So, 160 grams of yogurt has 1.85 gram fat.

let us assume x % of 160 = 1.85

or, x = 1.16%

Now, 15% of 1.85 g = 0.2775 g

So, the needed fat content = 1.85 g - 0.2775 g = 1.5725 g

⇒ 1.16 % of m = 1.5725 g

Solving for the value of m, we get:

m = 135. 56 g

1 gram = 0.035274 oz

⇒ 135. 56 g = 0.035274 oz x 135. 56 = 4.781738282 ≈ 4.8 oz

Hence, the new container will have 4.8 oz of yogurt.
