Mrs. pine took tennis lessons. she traveled 15 miles one way at an average cost of $0.45 per mile. her racket cost $84, balls cost 15.50, shoes cost $47.00, her warm-up was $32, and her shorts were on sale for $22. she paid 5% sales tax on her equipment and $25.00 per lesson for 10 lessons. including the cost of round-trip travel for all 10 lessons, what did this cost?

Round trip travel: 2*15miles*$0.45/mile = $13.5

Equipment: $84 + $15.50 + $47 + $32 + $22 = $200.50

Tax = $200.50 * 5%/100 = 10.025

Lessons: $25*10 = $250

Total cost = 13.5 + 200.5 + 10.025 + 250 = $474.025

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 )
