A book with a base price of $15.75 is marked up by 65%. What is the new price, to the nearest cent?

Vaselesa [24]

15,75 - 100 %

100 % = 100/100 = 1

Then every number multiplied by 1 is 100 % of itself.

If the book was marked up 65% of what is was before, it makes a price of 165% when compared to the original.

165% = 165/ 100 = 1,65

15,75 . 1,65 = 25,9875

25,99 is the nearest option.

a)25,99
