Question

Игрушечная дорога стоила 4500 руб. На распродаже цена понизилась на 30%. После распродажи цена была увеличина на 40%. Сколько стала стоить игрушечная дорога после распродожи?

Answer 1

4500/100%= 45(руб) цена 1%
45*(100%-30%)=3150(руб) цена во время распродажи
3150*1.4=4410(руб) цена после распродажи

Answer 2

Составим пропорцию
4500 - 100
х - 30

х=4500*30/100=1350 руб на сколько изменилась цена
4500-1350=3150 руб это цена после понижения на 30 процентов

3150-100
х-40

х=3150*40/100=1260 руб на сколько изменилась цена
3150+1260=4410 руб

Answer 3

Calculation of the final price of the toy train set after the sale:

To calculate the final price of the toy train set after the sale, we need to follow these steps:

1. Calculate the price reduction during the sale. 2. Calculate the price increase after the sale.

Let's break down the calculation:

1. Price reduction during the sale: - The toy train set initially cost 4500 rubles. - The price was reduced by 30% during the sale. - To calculate the price reduction, we multiply the initial price by the percentage reduction: 4500 * 0.30 = 1350 rubles. - The price was reduced by 1350 rubles during the sale.

2. Price increase after the sale: - After the sale, the price was increased by 40%. - To calculate the price increase, we add the price reduction to the initial price and then multiply it by the percentage increase: (4500 - 1350) * 0.40 = 1260 rubles. - The price was increased by 1260 rubles after the sale.

3. Calculate the final price: - To calculate the final price, we add the price increase to the reduced price: 4500 - 1350 + 1260 = 4410 rubles.

Therefore, the toy train set cost 4410 rubles after the sale.

Please note that the calculations are based on the information provided and assume that the price reduction and increase percentages are applied to the original price.
