Question 942217: A couple does not wish to spend more than $70 for dinner at a restaurant. If a sales tax of 5% is added to the bill and they plan to tip 20% after the tax has been added, what is the most they can spend for the meal?

You can put this solution on YOUR website! x = cost of meal before tax (dollars)

assume tip is calculated on x (before tax), this is usually done:
---
meal + tax + tip = 70
x + 0.05x + 0.20x = 70
1.25x = 70
x = 70/1.25
x = 56.00
---
now, assume tip is calculated on x+tax (after tax), this is usually not done:
meal + tax + tip = 70
x + 0.05x + 0.20*(1.05x) = 70
x + 0.05x + 0.21x = 70
1.26x = 70
x = 70/1.26
x = 55.56
