Question

Аня подсчитала что цена юбки составляет 80% её денег а цена блузки 60% её денег.И если дедушка даст ей ещё 96 рублей то она сможет купить обе вещи.Сколько стоит блузка и сколько стоит юбка?

Answer 1

Возьмем за X lденьги, которые у нее есть, тогда 
0,8х+0,6х=96+х
1,4х=96+х
1,4х-х=96
0,4х=96
х=240
80% от 240 это 192 - юбка
60% = 144 - блузка 
итак 192+144+336
336-96 =240 из которых 96 дедушкины

Answer 2

Calculation of the Prices

To calculate the prices of the blouse and skirt, we can set up the following equations based on the given information:

Let x be the price of the blouse and y be the price of the skirt.

According to the given information, the price of the skirt is 80% of the total money Ania has, and the price of the blouse is 60% of the total money Ania has. We can express this as:

0.8 * Ania's money = y 0.6 * Ania's money = x Ania's money + 96 rubles = x + y

Solving the Equations

We can solve these equations to find the values of x and y.

From the first equation, we can express Ania's money in terms of y:

Ania's money = y / 0.8

Substituting this into the second equation, we get:

y / 0.8 + 96 = x + y

Simplifying the equation:

y / 0.8 + 96 = x + y y + 96 * 0.8 = x + y y + 76.8 = x + y 76.8 = x

Therefore, the price of the blouse (x) is 76.8 rubles, and the price of the skirt (y) is 96 rubles.

Answer

The blouse costs 76.8 rubles, and the skirt costs 96 rubles.
