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

Answers

The domain is the x coordinates, while the range is the y coordinates. 

B) Domain: {3, 0, 4, 2}; Range: {4, 1, -6, 17} 

This choice is correct because the domain is shown as the x values, and range is the y value,
