Answer 1

To find out how much the item originally cost before the sale, we can use a simple calculation. Let's solve each problem step by step:

1. The item was discounted by 50% and now costs 820 rubles. To find the original price, we can use the formula:

Original Price = Sale Price / (1 - Discount)

Plugging in the given values, we have:

Original Price = 820 / (1 - 0.5) = 820 / 0.5 = 1640 rubles.

Therefore, the item originally cost 1640 rubles.

2. The item was discounted by 40% and now costs 630 rubles. Using the same formula as before:

Original Price = 630 / (1 - 0.4) = 630 / 0.6 = 1050 rubles.

Therefore, the item originally cost 1050 rubles.
