Answer 1

1)7250*0,12=870 руб скидка
2)7250-870=6380 руб цена после понижения

1)2кг-8%
Х- 100%
(2*100):8=25 кг молока потребуется

Answer 2

Answer:

1. To calculate the price of the item after a 12% decrease, we can use the formula:

New Price = Initial Price - (Initial Price * Decrease Percentage)

Plugging in the values, we have:

New Price = 7250 - (7250 * 0.12)

Simplifying the equation:

New Price = 7250 - 870

Therefore, the price after the decrease is 6380.

2. To determine the amount of milk needed to obtain 2 kg of cream, we need to consider that cream contains 8% fat. This means that for every 100 grams of cream, 8 grams are fat and the remaining 92 grams are milk.

Let's assume that the cream is pure fat. Since 2 kg is equal to 2000 grams, we can calculate the amount of cream in grams by multiplying 2000 by 8%:

Amount of cream = 2000 * 0.08 = 160 grams

Since cream is 8% of the total weight, the remaining 92% is milk. To find the amount of milk needed, we can use the following equation:

Amount of milk = (Amount of cream / Cream Percentage) * Milk Percentage

Plugging in the values, we have:

Amount of milk = (160 / 8) * 92

Simplifying the equation:

Amount of milk = 20 * 92

Therefore, 1840 grams of milk are needed to obtain 2 kg of cream.
