Adding qty box and total price in cart page

[tharanithar-r]

Till now If the user want to add more quantity of same book it showing in a extra card instead of that I can add qty box with increasing and decreasing within a one card for one book. And also there is no total estimated price showing in cart page it is available only in the payment page, so I can add total price in the cart page also. Kindly assign this issue to me.
