The demand equation for a certain product is given by \( p = 106 - 0.08 x \) , where \( p \) is the unit price (in dollars) of the product and \( x \) is the number of units produced. The total revenue obtained by producing and selling \( x \) units is given by \( R = x p \) . 

Determine prices \( p \) that would yield a revenue of \( 8140 \) dollars. 

Lowest such price \( = \) ______ dollars

Highest such price \( = 99.48 \) dollars
