4 1) В магазине было продано 1250 пар обуви. 48% всей обуви соста-вила женская обувь, 28% мужская, а остальные - детская. Сколько паркаждого вида обуви было продано в магазине?2) В магазине было 120 пар детской и 84 пары женской обуви. За не-делю продали 25% всей обуви. На сколько пар детской обуви было про-дано больше, чем женской? помогите плиз​

Answer 1

Ответ:

1250 это 100%. 100-48-28 это 24. %24 детская оьувь.

1250 умножить на 0.48 это 600.это 600 пар женской обувы. 1250 умножить на 0.28 это 350. это 350 пар мужской обуви. остальное это детская обувь 300.

вторая задача

100:25 это 4. продали одну четвертую обуви.

120 делить на 4 это 30. 84 делить на 4 это 21.

30-21= 9. на 9 больше

Answer 2

To solve these problems, we can use a system of equations. Let's define the variables:

- Let x represent the number of pairs of women's shoes sold. - Let y represent the number of pairs of men's shoes sold. - Let z represent the number of pairs of children's shoes sold.

Now let's solve the problems step by step.

Problem 1:

In the store, 48% of all shoes sold were women's shoes, 28% were men's shoes, and the rest were children's shoes. The total number of shoes sold was 1250 pairs.

We can set up the following equations:

x + y + z = 1250 (equation 1) x = 0.48 * 1250 (equation 2) y = 0.28 * 1250 (equation 3)

To find the values of x, y, and z, we can solve this system of equations.

From equation 2, we have: x = 0.48 * 1250 = 600

From equation 3, we have: y = 0.28 * 1250 = 350

Substituting the values of x and y into equation 1, we have: 600 + 350 + z = 1250 950 + z = 1250 z = 1250 - 950 z = 300

Therefore, in the store, 600 pairs of women's shoes, 350 pairs of men's shoes, and 300 pairs of children's shoes were sold.

Problem 2:

In the store, there were 120 pairs of children's shoes and 84 pairs of women's shoes. 25% of all shoes were sold.

Let's define the following variables: - Let a represent the number of pairs of children's shoes sold. - Let b represent the number of pairs of women's shoes sold.

We can set up the following equations:

a + b = 0.25 * (120 + 84) (equation 4) a = 120 (equation 5) b = 84 (equation 6)

To find the values of a and b, we can solve this system of equations.

From equation 5, we have: a = 120

From equation 6, we have: b = 84

Substituting the values of a and b into equation 4, we have: 120 + 84 = 0.25 * (120 + 84) 204 = 0.25 * 204 204 = 51

Therefore, 120 pairs of children's shoes were sold, and 84 pairs of women's shoes were sold.

To find the difference between the number of pairs of children's shoes sold and the number of pairs of women's shoes sold, we subtract the values: 120 - 84 = 36

Therefore, there were 36 more pairs of children's shoes sold than women's shoes.

I hope this helps! Let me know if you have any further questions.
