Cole orders 4 bags of salted potato chips, 3 bags of sour cream, and chive potato chips, and 2 bags of barbecue potato chips. Cole finds the cost using the expression 4x + 2x where x is the cost of one bag of chips. Explain a more efficient way to use an expression to work out thew cost. Choose the correct answer below. A. Cole can use the expression ( 4+3+2)x B. He can use the expression (4 + 2) x + 3x C. He can use the expression x+x+x+x+x+X D. He can use 9x E. He can use ( = 2)x +4 x
