Answer:
D. 50
Explanation:
Suppose we denote the "value" as the variable x. Now, we convert the words into mathematical equations:
40% "of" x "is" 20.
"Of" usually means multiply, and "is" usually means equal, so:
40% * x = 20
40/100 * x = 20
0.40 * x = 20
Now, we can just solve by dividing both sides by 0.40:
x = 50
Thus, our value is 50, so D.
Hope this helps!
