Well honey, if you're trying to figure out how many 20 dollar bills you need to make 150 bucks, the answer is 7.5. But since we can't have half a bill, you'll need 8 bills to make it happen. Just make sure you're not trying to pay with half a bill at the store, they might not appreciate that!
To determine how many $20 bills make up $150, you would divide $150 by $20. This calculation results in 7.5, but since you cannot have a fraction of a bill, you would have to round down to the nearest whole number. Therefore, you would need 7 $20 bills to make up $150.
