Answer 3

Calculation of the New Price

To calculate the new price of the book after a 20% increase, we need to add 20% of the original price to the original price itself.

Given that the original price of the book was 320 rubles, we can calculate the increase as follows:

320 rubles + (20% of 320 rubles)

To find 20% of 320 rubles, we multiply 320 by 0.20:

320 rubles * 0.20 = 64 rubles

Adding the increase to the original price:

320 rubles + 64 rubles = 384 rubles

Therefore, the new price of the book is 384 rubles.

Please note that the calculation assumes a simple percentage increase without any additional factors or discounts.
