Which of the following is true when using summation variables?
A)The number of constraints will stay the same as in a formulation without the use of summation variables.
B)The number of variables will stay the same as in a formulation without the use of summation variables.
C)There are typically fewer non-zero input coefficients on the left side of the constraints.
D)Percentage constraints cannot be formulated without the use of summation variables.

When using summation variables, the left side of the constraints will have one non-zero coefficient, which leads to fewer non-zero input coefficients on the left side of the constraints. The number of constraints and variables may or may not change, depending on the specific problem. Percentage constraints can be formulated without the use of summation variables by properly setting up the problem.
