Answer:
The normal undiscounted price of the book is $17.25.
Step-by-step explanation:
This question can be solved using a rule of three.
After a 35% discount, a book costs $11.21
This means that $11.21 is 100-35 = 65% = 0.65 of the original price x.
How much is x, which is 100% = 1?
$11.21 - 0.65
$x - 1



The normal undiscounted price of the book is $17.25.

Answer:
During the first year he had an annual interest of 12%, and in the second year of 25%
Step-by-step explanation:
To calculate the interest of the first year:
(Initial capital of the first year / final capital of the first year) - 1 = interest of the first year
(300/336) - 1 = 0.12 = 12%
To calculate the interest of the second year:
(Initial capital of the secondyear / final capital of the second year) - 1 = interest of the second year
(336/420) - 1 = 0.25 = 25%
