The Guess аnd Check 2.0 tаble belоw shоws guesses аrranged tо solve the question posed in this problem: A group of friends went to a local restaurant after the school football game on Saturday night. They all ordered from the menu and forgot to tell the server to give them separate checks. The bill totaled $252, including tip. They decided to split the bill evenly, and they figured out how much each of them owed. By then three people said they had no money. They rest of the people each had to chip in $2.40 extra to cover the tab. How many people were in the group? ???? (Column A) Cost per person initially The cost for the three people without money The amount extra each of the remaining people had to pay Results Thoughts 10 $252 / 10 = $25.20 $25.20 x 3 = $75.60 $75.60 / (10 - 3) = $10.80 $10.80 does not equal $2.40. The extra each person had to pay was too big. Try to split the bill among more people. 15 $252 / 15 = $16.80 $16.80 x 3 = $50.40 $50.40 / (15 - 3) = $4.20 $4.20 is still greater than $2.40 The extra to pay is still too much but getting much closer Choose the most appropriate title for Column A currently labeled as "????"
