In this problem, cost, revenue, and profit are in dollars and x is the number of units. Suppose that the total revenue function is given by src="https://sciemce.com/media/3/ppg__cognero__Chapter_09_Derivatives__media__c8d839c1-b79b-4fed-81cd-34d4650bedd8.PNG" class="wirisformula" align="middle" style="vertical-align: middle;" data-wiris-created="true" varid="variable_id_field" variablename="impvar_7dd24da295d64e7ea8b6ffb1c" />, and explain what this value represents. Round your answer to two decimal places.
