Rose purchased 2 packs of red pens, 4 packs of black pens, and 3 packs of blue pens. The cost of each pack of pens was $2.50. Th
e expression $2.50 • 2 + $2.50 • 4 + $2.50 • 3 represents the total cost of the pens. Which expression also represents the total cost of the pens? A. $2.50 • 2 • 4 • 3 B. $2.50 • (2 + 4 + 3) C. $2.50 + (2 • 4 • 3) D. $2.50 + 2 + 4 + 3
If she bought 9 packs of pens at 2.50$ each then she spent 22.50$ on pens. If you add up the packs and multiply by the price you get your answer. 2.50 * (2+3+4) = 22.50$
