I do not see the statements.
The product of 379 and 8 is 3032, that other answer was wrong they answered with the sum (addition) not the product (multiplication)
So I think you have to find 11% of 24 and that is 11/100 x 24 = 2.64$. Then you reduce it to the real price 24-2.64= 21.36$ (the new prize). I might be completly wrong but I hope this helps
