Calculation of the Price of Gasoline in November

To calculate the price of gasoline in November, we need to consider the initial price in January, the increase in price by 5% in July, and the additional increase of 10% in November.

Let's start with the initial price in January, which was 68 rubles per liter.

In July, the price increased by 5%. To calculate the new price, we can multiply the initial price by 1.05:

68 rubles * 1.05 = 71.4 rubles per liter.

Now, let's calculate the price in November. We need to apply an additional increase of 10% to the price in July. To do this, we can multiply the price in July by 1.10:

71.4 rubles * 1.10 = 78.54 rubles per liter.

Therefore, the price of gasoline in November was approximately 78.54 rubles per liter.
