After adding a tip, the total lunch cost was $32.24. What percentage tip did they give? Enter your answer to the nearest percentage.
To find the tip percentage, we need to know the original cost of the lunch.
Let's assume the original cost of the lunch without the tip is X.
The total lunch cost after adding the tip is given as $32.24.
So, we can set up the equation:
X + tip = $32.24
Since we want to find the tip percentage, let's express the tip as a percentage of the original cost of the lunch:
tip = X * (tip percentage/100)
Plugging this into the equation, we get:
X + X * (tip percentage/100) = $32.24
Simplifying the equation, we have:
X * (1 + tip percentage/100) = $32.24
Now, we can solve for the tip percentage.
Dividing both sides of the equation by X, we get:
1 + tip percentage/100 = 32.24/X
Subtracting 1 from both sides of the equation, we have:
tip percentage/100 = (32.24/X) - 1
Multiplying both sides of the equation by 100, we get:
tip percentage = 100 * ((32.24/X) - 1)
Since we do not have the value of X, we cannot determine the exact tip percentage.
