Answer:
$30
Step-by-step explanation:
Let the price of sweatshirt be $x.
Discount percentage = 30%
Discount in dollars = 30% of $x
Discount in dollars = 30/100 of $x = $ 30x/100
Given that discount in $ is 9
thus
30x/100 = 9
x = 9*100/30 = 30
Thus, the original price is $30
Total is 68 and the perm is 2 times as much as her haircut and her lunch is $5
so...
2h+h+5= 68 (add like terms)
3h+5 = 68 (subtract 5 from both sides)
-5 - 5
3h = 63 (divide by 3)
h= 21
so if her haircut is 21 dollars
21*2= $42
her perm cost 42 dollars
