Answer 3

Solving the Equation for the Cost of Each Garland

To solve this problem, we can use the given information to set up an equation and solve for the cost of garlands on the first and second days.

Let's denote the cost of each garland as r (in Tenge). According to the given information, 50 garlands were bought on the first day and 30 garlands on the second day, both at the same price. The total amount paid was 6,400 Tenge.

We can set up the following equation to represent the given information: 50r + 30r = 6400

Calculating the Cost for Each Day

Now, let's solve for r to find the cost of each garland.

50r + 30r = 6400 80r = 6400 r = 6400 / 80 r = 80

So, the cost of each garland is 80 Tenge.

Total Cost for Each Day

Using the calculated cost of each garland, we can find the total cost for each day.

- First Day: 50 garlands were bought, so the total cost on the first day is 50 * 80 = 4000 Tenge. - Second Day: 30 garlands were bought, so the total cost on the second day is 30 * 80 = 2400 Tenge.

Therefore, the amount paid on the first day was 4000 Tenge, and on the second day was 2400 Tenge.

So, the amount paid in the first day was 4000 Tenge, and in the second day was 2400 Tenge.
