Heather paid \( \$ 2,022.30 \) for a computer. If the price paid includes a \( 7 \% \) sales tax, which of the following equations can be used to determine the price of the computer after tax? (Let \( x \) represent the cost of the computer and \( y \) represent the total cost after tax.) A. \( y=1.7 x \) B. \( y=0.93 x \) C. \( y=x+7 x \) D. \( y=1.07 x \)
