Ответы на вопрос

7*60=420 руб за куклы



2.60*7=420



Problem Statement:
In a kindergarten, several balls were purchased for 40 rubles each, and an equal number of dolls were purchased for 60 rubles each. If a total of 280 rubles was spent on the balls, how many dolls were purchased?
Solution:
Let's solve this problem step by step.
1. Let's assume the number of balls and dolls purchased is 'x'.
2. The cost of each ball is 40 rubles, so the total cost of the balls is 40 * x = 40x rubles.
3. The cost of each doll is 60 rubles, so the total cost of the dolls is 60 * x = 60x rubles.
4. According to the problem, the total cost of the balls is 280 rubles. So we can write the equation: 40x = 280.
5. To find the value of 'x', we can solve the equation: 40x = 280.
Dividing both sides of the equation by 40, we get: x = 280 / 40 = 7.
Therefore, the number of dolls purchased is 7.
Expression:
The expression for the problem can be written as: 40x = 280.
Where: - 'x' represents the number of balls and dolls purchased. - 40 represents the cost of each ball. - 280 represents the total cost of the balls.
