Suppose that wi're making and seling some widget and the profit (in dollars) when making x widgets is P(x)=30z0.07z2600. Find the marginal profit formula and the marginal average prost formula. Then determine the marpinal peofit and the marginal average proft when 43 widgets are mode. The marginat profit tunction is P(x)= If we're already making 43 widgots and if we increase production by one widget our profit wil change by $ The marginal average profic function is P(x)= If we're already making 43 widgets and it we increase production by one widget our average prots per widget will change by 9
