A company can model the profit it makes on selling an item at price x by using the expression 2000x - 10,500. A second item sold at the same price brings in a profit of 1850x - 11,600. Write and simplify an expression that reflects the total profit from the sale of both items. 15x + 34 -14x + 26 2x - 4 19x + 1 -4x - 10 -5x - 1 15x + 31 -3x + 12 4x + 7 22x + 23 2x + 11 -10x - 11 -16x + 13 -x + 5 4x - 3 -10x -8x - 13 -9x + 26 3x - 2 3850x - 22,100 Math Accelerated • Chapter 7 Algebraic Expressions
