Answer 3

Calculation of the Original Price of the Kettle

To calculate the original price of the kettle before the price reduction, we can use the information given. The price of the kettle after the reduction is 316 rubles, and the reduction was 21%.

To find the original price, we can set up the following equation:

Original Price - (Original Price * 21%) = 316 rubles

Let's solve this equation to find the original price.

Solution:

Let's assume the original price of the kettle is x rubles.

According to the equation, we have:

x - (x * 21%) = 316 rubles

To calculate the 21% reduction, we need to multiply the original price by 0.21:

x - (0.21x) = 316 rubles

Combining like terms:

0.79x = 316 rubles

Now, we can solve for x by dividing both sides of the equation by 0.79:

x = 316 rubles / 0.79

Calculating the value:

x = 400 rubles

Therefore, the original price of the kettle before the price reduction was 400 rubles.

Answer:

The original price of the kettle before the price reduction was 400 rubles.
