The per-unit price p (in dollars) of a popular toy when x units (in thousands) are produced is modeled by the function 12-0.025x p = 12 − 0.025 x . The revenue (in thousands of dollars) is the product of the price per unit and the number of units (in thousands) produced. So the revenue function is given by r ( x ) = x p , or rather: r ( x ) = x ( 12 − 0.025 x ) According to this function, how many single units should be produced for the revenue to equal $440,000? There will be two answers, type the least answer into the box. Be careful with units, remember that x represents thousands of units and r ( x ) represents thousands of dollars.
