Teacher: Now, understand the problem? Solve this instance: Would you like some more coffee ?  No thanks . I'm full . We need to find our waitress and get our bill .  The waitress is bringing the bill right now .  This waitress has really been on top of things , hasn't she ?  Yes , this waitress did a great job .  OK , let's see what the damage is . The total for our meal is $ 36.00 .  What do you think would be the right amount to leave for a tip ?  Fifteen percent is a normal tip , but she really did a great job . What do you think about 20 % this time ?  Yes , 20 % would be perfect .  Her tip will end up being $ 7.20 plus the bill of $ 36.00 . The total will be $ 43.20 .  Yes , that was one fantastic meal !  I agree . Maybe we can come back again next week .
