“I’m gonna teach you a trick,” she told viewers, explaining that there’s no need to pull out a calculator when figuring out a tip.

Holding up a receipt, Alex broke it down: “To calculate a 20% tip, just move the decimal point one place to the left.”

Using her own bill as an example, which totaled $64.93, she explained, “That gives you approximately $6.50—that’s 10%. To make it a 20% tip, simply double it. So, you’d leave a $13 tip.”

She summed it up simply: “Just move the decimal over and double it.”
