You have 7 lines and per 3 lines you're charged $14.50. 7 divided by 3 is 2.33333333. 14.50 X 2 = $29. Now you solve for the unit price ( the cost per one line and multiply that by 2 ) So the unit price is about $4.83. $4.83 x 2.33333 = $11.27. The total cost would be about $40.27.
I hope this helps :)
640=5×2⁷ so ⁷√640=2×⁷√5. So the expression can be simplified to 2 ⁷√6−5 ⁷√5. Note that -6=-1×6, and the 7th root of -1 is -1. This makes (-2)×(-1)=2, the coefficient of ⁷√6.
