I think 73 because:
First I did '1,000 + x = 2,450'
Then I got 'x = 1450'
But then 20 can't go into 1450
So I just add another 10 to 1450 an got 1460
1460/20 = 73!
Hope this helps an is correct!!!
Answer:
Step-by-step explanation:
Let's start by decoding this :)
First lets do 60% more than 10; 16 (mental math)
Next, lets do 20% less than 16; x/16 = 80/100 (Equation)
After solving by cross multiplying & then simplifying (make sure both denominators are 100), you should get 12.8 as your final #! Hope this helped.
