Question

Стоимость за год уменьшился на 30% и стала составлять 3360 . Сколько стоило первоначально?

Answer 1

х- исходная стоимость

х-100%

3360-70%

3360*100/70=4800

Answer 2

Calculation of the Initial Cost

To calculate the initial cost, we can use the information provided that the cost for one year decreased by 30% and became 3360. Let's denote the initial cost as x.

The equation can be set up as follows:

x - 30% of x = 3360

To solve for x, we can rewrite the equation as:

x - 0.3x = 3360

Simplifying the equation:

0.7x = 3360

Dividing both sides of the equation by 0.7:

x = 3360 / 0.7

Calculating the value of x:

x = 4800

Therefore, the initial cost was 4800.
