Answer:
60 dollars!
Explanation:
So, 12 oranges cost $36 dollars.
Now, we can solve this by finding the value for only <u>one</u> orange, then multiplying that by 20 to get our answer!
So, the value of one orange is $36 / 12 = $3. One orange is worth $3 dollars.
So, 20 oranges will be worth 20 * 3 = $60 dollars!
Answer:
13.4%
