Problema Solution
Suppose a college bookstore buys a textbook from a publishing company and then marks up the price they paid for the book 33% and sells it to a student at the marked-up price. If the student pays $110 for the textbook, what did the bookstore pay for it? Round your answer to the nearest cent.
Answer provided by our tutors
let 'x' represent the amount the book cost the bookstore, then 'x + 0.33x' represents the amount paid by the student
110 = x + 0.33x
solving for 'x' we have x=82.706
the bookstore paid approximately $82.71
