To the nearest ten thousand, the population of Vermont was estimated to be about 620,000 in 2008. What might have been the exact population of Vermont in 2008?

Solve the equations using the substitution method: 4x -2y =22 2x + 4y = 6
Answers
we have that 4x -2y =22------> clear variable y 2y=4x-22--------> y=4x/2-22/2---------> y=2x-11-----> equation 1 2x + 4y = 6------> equation 2
substitute equation 1 in equation 2 2x+4*[2x-11]=6-----> 2x+8x-44=6----> 10x=50------> x=5 then y=2x-11----> y=2*5-11----> y=-1

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
