So the book guy mark downed the price of the books by 46%, also known as 0.46. All decimals are less than 1. So then, what you do is you take b, which is the variable defining the price of the book, then you multiply it by 0.46. So the answer of b would be b x 0.46. For C, you must do 29 x 0.54, and that will give you the answer for C. Finally, in D, take the answer you got in C, and subtract that by 29. This will give you your answer.
First we need to calculate the total payments by multiplying the payment per week times number of weeks in a year times 3 years
Total payments=128×52weeks×3years
=19,968
Subtract the amount borrowed from the total payments to get the interest charged
Interest charged
=19,968−13,450=6,518
