If the hostess had used up 450 grams of butter, then she would have had 550 grams, in fact, 475 grams

If the hostess had used up 450 grams of butter, then she would have had 550 grams, in fact, 475 grams remained, how many grams of oil the hostess used up.

Presumably consumed – 450 g of oil

Presumably left – 550 g

In reality – 475 g left

Did you really use up -? r

Based on the fact that if the hostess consumed 450 grams of oil, then she would have 550 g left, we find the initial mass of oil:

1) 450 + 550 = 1000 (g) – there was oil at the beginning.

The consumption of oil implies a subtraction action, so knowing that at the beginning of the oil there was 1000 g, but in reality there were 475 g left, then:

2) 1000 – 475 = 525 (g) – used oils in reality.

Answer: 525 BC
