Scenario
In your Social Studies Integrated Activity you have investigated the use of 5 different barges that were sold by farmers on the dock to Northern Merchants or Colonies. I do hope you remember them, since you will assume the role of a farmer, select one barge and represent your earning linearly. As a farmer you have worked for countless hours preparing your crop for harvesting and to sell them to the Northern Merchants. The basic earning of a farmer for the first 50 pounds or liters of your selected barge is $250. An additional commission of 25% is paid for each pound or liter exceeding the first 50 pounds or liters. Activity  1. Write a linear equation to represent your earning for selling your produce. Earning =? 2. Construct a graph to represent your linear equation. 3. You are expected to label all axes of your graph, use an appropriate scale to construct the graph, and give the graph a title. Please ensure that your graph is accurately and neatly drawn.

4. Use your equation to calculate the earnings of a farmer if he sells 165 pounds of cotton and 72 liters of brandy.
