Ms. Fisher needs to order supplies for next year. She will need 1200 pencils. Pencils come in boxes of 24. If she orders 57 boxes, will she have enough? How do you know?
Yes, you do have enough pencils because first, I multiply 5x4=14 and 7x2+2=16 (168). Then, I multiply 4x5=20 and 2x5=10 (120). Lastly, I add 168+120=1,368. Don't forget to send a yearbook for me!
