Question 78744: if the total bill at a restaurant, cincluding a 15% tip, is $65.32, what ws the cost of the meal Answer by bucky(2189) (Show Source):
You can put this solution on YOUR website! If you are handed the bill for the meal and the cost is x, if you tip 15% you multiply
x by 0.15 and add that amount to the bill. In algebraic form this is x + 0.15x
.
This sums to 1.15x. And the problem tells you that this amount equals $65.32. In equation
form this is:
.
.
Solve this equation by dividing both sides by the multiplier of x which is 1.15.
.
When you do, this equation becomes:
.
.
So the cost of the meal was $56.80. The tip was 15% of that or $56.80 * 0.15 = $8.52
and the total bill was $56.80 + $8.52 = $65.32 ... just as the problem said it was.
.
Hope this helps you to understand the common practice of restaurant tipping ... a skill
you are likely to use at sometime or another.
