Jennifer sells paper by the pound. It costs Jennifer $10.00 to ship any package of paper. For every pound of paper Jennifer sell she earns a profit of $3.00. Which graph could Jennifer use to calculate her total profit from selling and shipping any package? The x-axis represents the weight of any package (in pounds) and the y-axis represents Jennifer's total profit (in dollars).
costs her 10 so minus 10 from profit earns 3 per pound so if she sells x pounds and profit is y then
profit=number of pound sold times cost per pound minus shipping or y=3x-10 the equation is y=3x-10 it intercepts the y axis at y=-10 intercepts the x axis at x=10/3 some points on the graph are (0,-10) (1,-7) (2,-4), (3,-1), (4,2) etc see which one is that graph
