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. blank (b - blank) = blank
From the given information, we can deduce that Stan tipped the waiter 20% on the reduced bill, which was $15.
Let's set up an equation to solve for the reduced bill, which we'll call "b":
(b - blank) = blank
We know that Stan tipped 20% on the reduced bill, so the tip amount can be expressed as 0.20b.
According to the problem, the tip amount is $15:
0.20b = $15
To solve for b, we can divide both sides of the equation by 0.20:
b = $15 / 0.20
Simplifying the equation, we get:
b = $75
Therefore, the reduced bill (b) is $75.
