Multiply $30 by 0.15 to find the amount discounted: 30x0.15=$4.50
Now subtract 4.5 from 30 to find the final cost of the bat. 30-4.5= $25.50
The final price of the $30 bat after applying a 15% discount is $25.50. This is calculated by finding 15% of $30, which is $4.50, and then subtracting that amount from the original price. Therefore, the final price is $30 - $4.50 = $25.50.
