Answer 1

A publisher marks up a textbook by 60%, and a bookstore further marks up the textbook by 25%. What percentage of the original cost do you pay?

Let

x ------> original cost

so

1) publisher marks up a textbook by 60%

cost=1.60x

2) bookstore further marks up the textbook by 25%

cost=1.60x(1.25)=2x

therefore

200%
