Calculating Mikhail's Initial Amount of Money

To calculate the initial amount of money Mikhail had, we can use the fact that he spent 45% of his money on a math textbook that costs 36 rubles.

Let's denote the initial amount of money Mikhail had as x.

The amount spent on the textbook can be calculated as 45% of x, which is 0.45x.

The cost of the textbook is given as 36 rubles.

We can set up the equation: x - 0.45x = 36

Solving for x: 0.55x = 36 x = 36 / 0.55 x ≈ 65.45

So, Mikhail initially had approximately 65.45 rubles.

Therefore, Mikhail initially had approximately 65.45 rubles.
