Answer 1

ответь изменился на 4.5

Answer 2

Пример:цена товара составляет100руб что составляет100% затем она была снижена на 5% находим какой стала цена 100:100=х:5; х=100*5:100; х=5;
цена на товар стала95руб.после чего ее увеличили на 10% находим какой стала цена 95:100=х:10; х=95*10:100; х=9,5; цена тавора повысиласьна 9руб.50коп. и
стала 95+9,5=104,5руб.
Первоначальная цена изменилась на 104,5-100=4руб.50коп.

Answer 3

Calculation of the Initial Price

To calculate the change in the initial price, we need to follow these steps:

1. Start with the original price. 2. Decrease the price by 5%. 3. Increase the resulting price by 10%.

Let's assume the initial price is P.

1. Decreasing the price by 5% gives us a new price of P - 0.05P. 2. Increasing the resulting price by 10% gives us the final price of (P - 0.05P) + 0.1(P - 0.05P).

To simplify the calculation, let's perform the calculations step by step:

1. P - 0.05P can be simplified to 0.95P. 2. (P - 0.05P) + 0.1(P - 0.05P) can be simplified to 1.05P.

Therefore, the final price after the 5% decrease and 10% increase is 1.05P.

To find the change in the initial price, we need to subtract the final price from the initial price:

Change in initial price = Final price - Initial price = 1.05P - P = 0.05P.

So, the initial price has decreased by 5% of the original price.

Please note that the specific value of the initial price (P) was not provided in the question, so we cannot determine the exact change in the initial price. However, we can conclude that the initial price has decreased by 5% based on the given information.
