Answer:
Step-by-step explanation:
Cost of meal = $6
Amount of tip = $0.90
To calculate the tip as a percentage of the total cost, divide amount
of tip by the total cost and multiply the result by 100;
Percentage of tip = (amount of tip/cost of meal ) *100
= (0.90 / 6)*100
= 0.15 *100
= 15%
Therefore Miss Holman tipped the waitress 15% of the total cost of the meal
