Use the model to answer the questions. A rectangle is divided into two sections by a vertical line. The left section is labeled inside with 260. The right section is labeled inside with B. The left edge of the rectangle is labeled 13. Across the top outside of the rectangle, the sections are labeled A tens, a plus sign above the vertical line, and C. Part A Carter wants to use the model above to solve 273 ÷ 13 . Explain how he would find parts A, B, and C of the model.
