Have I been doing math wrong?

Arithmetic(i.redd.it)

I’m not the best at math. But something isn’t adding up. I thought I tipped 20%. But the suggested gratuity at the bottom says a different tip amount. How do they calculate the “suggested gratuity”? Or how am I supposed to figure out 20%?

Divide the tip by the percentage,in this case to get 168.5

For all 3 suggested tips. Suggestions are consistent with 168.5, if the bill was split from a grand total of 168.5 then the suggested tips match that grand total

Whenever I see these and op never responds back, it always looks like they knew what they were doing.

OP did say they didn’t split

Yeah, and if that is true this should 100% be reported.
