Question

. Кондиционер стоил 16000 рублей. Сначала цену снизили на 30%, а потом эту сниженную цену повысили на 30%. Сколько стал стоить кондиционер после повышения цены?

Answer 1

1) 16000:100=160 - 1 %
2) 160*30=4800 - 30 %
3) 16000-4800=11200 - цена после понижения
4) 11200:100=112 - 1 %
5) 112*30=3360 - 30 %
6) 11200+3360=14560

Answer 2

Calculation of the New Price

To calculate the new price of the air conditioner after the price decrease and subsequent increase, we can follow these steps:

1. Start with the original price of the air conditioner, which is 16,000 rubles. 2. Apply a 30% decrease to the original price. This can be calculated by multiplying the original price by 0.7 (100% - 30% = 70%). 3. Calculate the decreased price by multiplying the original price by 0.7. 4. Apply a 30% increase to the decreased price. This can be calculated by multiplying the decreased price by 1.3 (100% + 30% = 130%). 5. Calculate the final price by multiplying the decreased price by 1.3.

Let's perform the calculations:

1. Original price: 16,000 rubles. 2. Decreased price: 16,000 * 0.7 = 11,200 rubles. 3. Increased price: 11,200 * 1.3 = 14,560 rubles.

Therefore, after the price increase, the air conditioner would cost 14,560 rubles.

Note: The calculations above assume that the percentage decrease and increase are applied to the original price. If the percentages are applied to the current price after each change, the final price may differ.
