Answer 2

Calculation of Prices

To calculate the prices of the items mentioned, we can use the given information and perform some calculations.

a) Price of the T-shirt:

The school blazer costs 450 rubles and is 5 times more expensive than the T-shirt. To find the price of the T-shirt, we can divide the price of the blazer by 5.

Price of the T-shirt = Price of the blazer / 5

Price of the T-shirt = 450 rubles / 5 = 90 rubles

Therefore, the T-shirt costs 90 rubles.

b) Prices of the Shirt, Pants, and Skirt:

The shirt is twice as expensive as the T-shirt, the pants are 90 rubles more expensive than the shirt, and the skirt is 30 rubles cheaper than the pants.

Let's calculate the prices step by step:

1. Price of the shirt: - The shirt is twice as expensive as the T-shirt. - Price of the shirt = Price of the T-shirt * 2 - Price of the shirt = 90 rubles * 2 = 180 rubles

2. Price of the pants: - The pants are 90 rubles more expensive than the shirt. - Price of the pants = Price of the shirt + 90 rubles - Price of the pants = 180 rubles + 90 rubles = 270 rubles

3. Price of the skirt: - The skirt is 30 rubles cheaper than the pants. - Price of the skirt = Price of the pants - 30 rubles - Price of the skirt = 270 rubles - 30 rubles = 240 rubles

Therefore, the prices are as follows: - The shirt costs 180 rubles. - The pants cost 270 rubles. - The skirt costs 240 rubles.

c) Price of the Sneakers:

The blazer is 59 rubles cheaper than the sneakers. To find the price of the sneakers, we can add 59 rubles to the price of the blazer.

Price of the sneakers = Price of the blazer + 59 rubles

Price of the sneakers = 450 rubles + 59 rubles = 509 rubles

Therefore, the sneakers cost 509 rubles.

Please note that the prices mentioned above are based on the given information and calculations.
