A company manufactures two types of fishing rods, standard and folding. The cost of manufacturing 3 folding rods and 2 standard is $45. If 6 standard and 10 folding rods were manufactured, the cost would be $140. Let x represent the cost of producing a standard fishing rod and let y represent the cost of producing a folding fishing rod. Write the equations that represent how to find the cost of each fishing rod type. 3x+2y=45 10x+6y=145 2x+3y=140 6x+10y=45 3x+2y=140 10x+6y=45 2x+3y=45 6x+10y=140
