Percent

What is percent?

Most states charge sales tax on items you purchase. Sales tax is a percent of the item’s price. A percent is a ratio of a number to 100.You can remember that percent means “per hundred.” For example, 8% means “8 per hundred,” or “8 out of 100.”

If a 1% sales tax goes to SPLOST that means:• For every $1.00 you spend, you pay $0.01 to splost.• For every $10.00 you spend, you pay $0.10 in sales tax.• For every $100 you spend, you pay $1 in sales tax.

Because percent means “per hundred,” 100% means “100 out of 100.” This is why 100% is often used to mean “all” or “the whole thing.”
