Eric got a haircut that cost $35. He left the seven dollar tip. What percentage did Eric leave as a tip?
To find the percentage of the tip, you divide the tip amount by the total cost of the haircut and tip, and then multiply by 100.
Tip amount: $7
Total cost of haircut and tip: $35 (haircut) + $7 (tip) = $42
Percentage tip left: (7 / 42) * 100 = 16.67%
So, Eric left a 16.67% tip.
