To find out what percent of the meal cost was the tip, we need to divide the tip amount by the total cost of the meal and then multiply by 100 to express the result as a percentage.
Tip amount = $22
Total cost of the meal = $147
Percentage of the meal cost represented by the tip:
(22/147).100 = 14.965
Rounded to the nearest whole percent, the tip represents approximately 15% of the meal cost.
