Question

Для ремонта класса купили 3 банки белой краски по 960 тенге и столько же банок мебельного лака по 530 тенге сколько стоит вся покупка нужно решить двумя способоми

Answer 1

1 способ. 
3 банки краски - 960 тенге 
3 банки лака - 530 тенге
960+530=1490 тенге - вся покупка

2 способ.
Пусть х - это вся покупка
Из условия 3 банки краски стоит 960 тенге, а 3 банки лака - 530 тенге, тогда 
х= 960+530
х=1490 тенге

Answer 2

This is a math problem that asks how much the purchase of paint and varnish for the classroom repair costs. There are two ways to solve it: by using arithmetic or algebra.

Using arithmetic, we can calculate the cost of each item separately and then add them up. The cost of 3 cans of white paint is 3 times 960 tenge, which is 2880 tenge. The cost of 3 cans of varnish is 3 times 530 tenge, which is 1590 tenge. The total cost of the purchase is 2880 tenge plus 1590 tenge, which is 4470 tenge.

Using algebra, we can introduce a variable x to represent the cost of one can of white paint and another variable y to represent the cost of one can of varnish. Then we can write an equation that expresses the total cost of the purchase in terms of x and y. The equation is 3x + 3y = C, where C is the total cost. We can substitute the given values of x and y into the equation and solve for C. The equation becomes 3 times 960 tenge plus 3 times 530 tenge equals C, which simplifies to 4470 tenge equals C. Therefore, the total cost of the purchase is 4470 tenge.

Both methods give the same answer, which is 4470 tenge. This is the detailed answer to the question. You can also find similar problems and solutions on the web . I hope this helps you.
