For books whose price is less than $10.00, the bookstore provides no discount; for books whose price is from $10.00 to $11.99, the discount is 2% of the price. For books whose price is from $12.00 to $13.99, the discount is 4% of the price. For books whose price is $14.00 or above, the discount is 6% of the price. Calculate the discount amou nt of each book. 4. The bookstore runs a reward program for its customers. For the book price up to $10.00, customers earn 10 reward points for each dollar. For prices above $10.00, customers earn 5 points for each additional dollar. For example, if the book price is $12.50, then the reward points is: 10 points for each dollar up to $10.00 and 5 points for each dollar of the remaining $2.50; that is, the reward points is (10 x 10) + [5 x 2.50] = 112.50 points. Calculate the reward points to be awarded for each book. Note that partial rewards points are awarded. 5.
