I don't really get what it mean by "A group of 10 friends had lunch together at a restaurant. The meal cost a total of $99.50, including a 15% tip. How much was the total bill for lunch before tip?"
Answers
don't mind how many frieds there were, they question doesn't ask about that
so original=100% plus a 15% tip 100%+15%=115%
the total WITH tip was 99.50
therefor 99.50=115% of total befoer tip
percent means parts out of 100 115%=115/100=1.15
'of' means multipy
99.50=1.15 times totalbeforetip divide both sides by 1.15 86.521=totalbeforetip round 86.52=totalbefretip
totalbeforetip=$86.52
