Answer:
20%
Step-by-step explanation:
25x.20=5
25-5=20
If you decrease a price by 20% you multiply the original cost by 0.8
So, if y times 0.8 = $12, then you do y=12/0.8 which is 15.
The original cost is $15.
You can multiply the top equation by 3 and the bottom equation by 2, so you get:
-6y = 42
+6y = 18
(You also multiply whatever is in front but it's cut off so...)
Then you can add the equations so you get:
(whatever numbers cut off are) = 60
Then you solve for the variable cut off and sub it into one of the equations and solve for y.
