0.5x+0.3y>=3 sorry I don't know how to make the less than or equal to sign Step-by-step explanation: he can buy X amount of gumballs if he buys Y amount of jawbreakers and that will be less than or equal to $3 to graph, you must plug the number O into the X spot and solve. 0.5(0) +0.3y>=3 next plug in for Y 0.5x+0.3(0) >=3 plot these two points on the graph and draw a line through them
