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
To find the increase from 1997 to 1998, you could substitute in numbers and then determine the percent increase based on those numbers.
Ex: 500 to 1000 (96-97)
1000 to 2000 (97-98)
Percent increase is (2000-1000)/1000 or 100% increase.
Testing another set of numbers will result in the same thing.
Ex: 200 to 400 (96-97)
400 to 800 (97-98)
Percent increase is (800-400)400 or 100% increase.
The percent increase is 100%.
