Agroup of tourists spends $168 to rent snorkels and fins. a total of 10 snorkels and 12 pairs of fins are rented. renting a snorkel costs three times as much as renting a pair of fins. how much does it cost to rent a snorkel?

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

f(x)=2/3x-8, which give g(x) the greatest value.
