It’s a simple math problem with a straightforward answer: to make a dollar using nickels, you’ll need precisely 20 of them. Why? Well, each nickel is worth five cents, and when you multiply that by 20, you get one dollar (5 x 20 = 100). So, if you’re ever in a pinch and need to make some change, remember that a stack of 20 nickels will get you there!
