Percentage of a future number?

Question

Mathematics

Hai people have, for example, an apple worth 400 rubles. Let's say I'm a merchant in a shop, I bought them from the villagers for 400 rubles. I need to Sell them with +100r. = it would seem for 500r. But alas, there is a 15% commission. (and it is calculated from the future number, for example, the same 500. - but I need to take into account this commission - so that I would still have 100 rubles and find out the final cost with the commission of the future price. The question is how to find out the future price, well, or the final amount (if it turns out I don’t know the price at which I will sell? - what would it be to calculate 15% from it and throw it on the price tag to 500r?)

Answer 1

This is a percentage problem. You need to divide the given number by a percentage expression and multiply the result by 100.
500 / 85 * 100 = 588.23529
