20/100 * 50=$10

$10.00 discount from the $50.00.
$50-$10=$40.00

Have $35.00.
$40-$35=$5.00
Need to borrow $5.00!!

Price of the book = $50

20% discount = 0.2 x 50 = $10

After discount, the price of the book is
$50 - $10 = $40

I have $35, so I need
$40 - $35 = $5 more

Answer: I need to borrow $5 from a friend.
