Stan took Lily to his friend’s restaurant on a date. The friend told the waiter to remove the $12 dessert from Stan’s bill. Stan tipped the waiter 20% on the reduced bill, which was a $15 tip
To calculate the original bill, we need to subtract the tip from the reduced bill.
Let's assume the reduced bill after removing the $12 dessert was R dollars.
Reduced bill = Original bill - $12
R = Original bill - $12
We also know that the tip is 20% of the reduced bill, which is $15.
Tip amount = 20% of R = $15
To find the original bill, we can set up an equation:
(R * 20%) = $15
Simplifying the equation, we have:
0.2R = $15
Dividing both sides by 0.2, we get:
R = $75
Now, we can find the original bill by adding the $12 dessert amount back to the reduced bill:
Original bill = R + $12
Original bill = $75 + $12
Original bill = $87
Therefore, the original bill before removing the dessert was $87.
