The correct answer is actually B.
Why?
20% is 0.2 in decimal form.
Estimate $22.50, and you get 20.
So, the estimate for the discount is B) 0.2(20)
Hope this helps! And if it does, please give me a Brainliest :)
Btw, took the test, and my answer is right, not sure it'll be for anyone who is seeing this too :(
