First, find 1/5 of $130, and then subtract that from the original price of the item, because it is a discount.
Divide the price of the item by 5.
130 ÷ 5 = 26
130 - 26 = 104
So, the price of the item (not including tax) is $104. Now, we must calculate the sales tax and then add that onto the price of the item, as tax is money collected by the government.
To calculate the tax, multiply the discounted price of the item by the percentage of tax, and then add it.
104 × 10% = 10.4
104 + 10.4 = 114.4
ANSWER:
The amount of money you paid fot the item is $114.4.
Hello : cos(3<span>θ) = -1 </span>cos(3θ) = cos(<span>π) </span>general solution in : R is 3θ = (2k+1)π k in Z θ = (2k+1)π/3 if θ in <span> [0 , 2</span>π] the solutions are : k=0 : x = π/3 k=1 : x = π k=2 : x = 5π/3
