While Leo was visiting his sister in Ashland, he bought a surfboard that was marked down 40% from an original price of $521.28. If the sales tax in Ashland is 10%, what was the total cost of the surfboard?

  $344.04

Step-by-step explanation:

The markdown multiplies the price by (1 -40%) = 0.60.

The tax multiplies the price by (1 +10%) = 1.10.

The two factors applied to the price make the final price be ...

  $521.28·0.60·1.10 = $344.04

The total cost of the surfboard was $344.04.

45.3592

step-by-step explanation:

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 )
