Hello!
There is a discount of 40%, which means that we will be subtracting 40% of the price, and then sales tax is basically additional money added to the price, so we will be adding that. 
65.00 * 40% = 26
65.00 - 26 = 39
So, the discounted price is $39. Now we must add tax on that. 
39 * 5% = 1.95
39 + 1.95 = 40.95
The final price of the jacket is $40.95. 
        
             
        
        
        
So the question tells to express the expression in your problem where N0 is N-naught and the symbol represent the lower case Greek letter lambda. So the best answer or expression would be that the lambda is the wavelength of the expression. I hope you are satisfied with my answer
