To solve for the percentage of the meal's cost was the tip, divide amount of tip over the cost of meal times 100 and add % sign to get the percentage. Since the tip was $5.40 and the meal costs $30, divide $5.40 by $30 then times 100 and add % sign.
> $5.4/$30 x100
> 0.18 x100
> 18 or 18%.
The tip was 18% of the meal's cost.
To calculate the total cost of the meal including the tip, add the cost of meal plus the amount of tip given. Since the tip was $5.40 and the meal costs $30, add $5.40 and $30 to get the total cost of the meal including the tip.
> $5.40 +$30
> $35.40
The total cost of the meal including the tip was $35.40.
