Answer 2

Answer:

Step-by-step explanation:

The answer in percentage terms is 27%.

I'm not going to bore you with Xs and Ys and some nebulous algebraic equation. Just try a real example.

Let us suppose the book is $10 and the publisher gives our seller a 30% commission which means he would normally get $3 in commission. Now if our seller offers a 10% discount on the $10 book the price would fall to $9. His commission will also drop by 10% which means he'll walk away with $2.70 which is 27% of $10.

To test your working try a book price of $50.

This time the seller’s commission is 30% of $50 which is $15. Now if he discounts the book by 10% he would sell the book for $45. His 30% commission would then be $13.50 (10% drop on $15). $13.50 is 27% of $50
