Answer:
The sale price is $27
Step-by-step explanation:
We will be multiplying fractions so you will set it up as 30% over 100% times 90
30 90
---- x ------
100 1
You can simplify 30/100 to 3/10:
3 90
--- x ----
10 1
You then cross simplify 90 and 10 to get 9 and 1:
3 9
--- x ----
1 1
Once you multiply, you get 27/1 which is then 27.
The sale price is $27.
Hope this helps! :)
