half of 60 persent is 30 percent so half of 36 is 18 so 18 plus ten more percent is 6 so 18 plus 6 is 24 and 24 plus 36 is 60 dollars so before the sale she had 60 dollars
1 headphone without the discount is $36, so if we multiply 0.40 by 36 we get 14.4 which is the amount of discount you get, so you have to add 36 by 14.4 and you get 50.40 which is the final price.
