Question

товар поступил в продажу по цене 3000 р. В конце каждой недели цена товара понижается на 10 % . Сколько будет стоить товар через 16 дней?

Answer 1

16 дней это чуть больше чем две недели. значит цена понизится 2 раза. ну и считаешь. допустим стоимость х. -10% = 0,9x и  ещё -10% = 0,81x

Если мы знаем, что х= 3000р, то будет стоить 0,81*3000 = 2430р

Answer 2

Calculating the Price of the Product

To calculate the price of the product after 16 days, we need to consider that the price decreases by 10% at the end of each week.

Let's break down the problem step by step:

1. The initial price of the product is 3000 rubles. 2. The price decreases by 10% at the end of each week.

To calculate the price after 16 days, we need to determine how many weeks have passed and calculate the price reduction accordingly.

Calculating the Number of Weeks

To calculate the number of weeks, we divide the number of days (16) by 7 (the number of days in a week) and take the integer part of the result. This will give us the number of complete weeks that have passed.

16 days / 7 days per week = 2 weeks (with a remainder of 2 days)

So, 2 complete weeks have passed.

Calculating the Price Reduction

Since the price decreases by 10% at the end of each week, we need to calculate the cumulative reduction in price for the 2 complete weeks.

To calculate the cumulative reduction, we multiply the initial price by 0.9 (to decrease it by 10%) for each week that has passed.

1st week: 3000 rubles * 0.9 = 2700 rubles 2nd week: 2700 rubles * 0.9 = 2430 rubles

Calculating the Remaining Days

After 2 complete weeks, we have 2 remaining days. We need to calculate the price reduction for these remaining days.

To calculate the price reduction for the remaining days, we multiply the current price (2430 rubles) by 0.9 (to decrease it by 10%).

Remaining days: 2430 rubles * 0.9 = 2187 rubles

Calculating the Final Price

To calculate the final price after 16 days, we add the cumulative reduction for the complete weeks (2430 rubles) to the reduction for the remaining days (2187 rubles).

Final price: 2430 rubles + 2187 rubles = 4617 rubles

Therefore, the product will cost 4617 rubles after 16 days.

Please note that this calculation assumes a consistent 10% reduction in price at the end of each week. If there are any additional factors or conditions that affect the price reduction, please provide more information for a more accurate calculation.
