Examples
Example: The expression 5(3x+1) can be rewritten equivalently as 15x+5.Example: If the expression 2x+3x represents the profit the cheerleading team can make when selling the same number of cupcakes, sold for $2 each, and brownies, sold for $3 each. The expression 5x can express the total profit.
