Question 465891:  A birthday celebration meal is $40.50 including tax. Find the total cost if a 15% tip is added to the cost.

You can  put this solution on YOUR website! 15% is equal to 0.15. .15 times 40.5 is 6.075, so $6.075 is the total tip. If we add this on to the original cost, we get $46.575. If we round this value to the nearest cent, we find that the total cost of the meal is $46.58.
