Tisha and her academic team are working to go to state finals. They must have a certain number of points, T, to advance. They have had three local matches, a, b and c, and will attend a district match. District match points count for twice the number of points than local matches do. Choose the equation that would help Tisha find how many points they need to earn in the district match, d, to advance. A:d equals T minus a minus b minus c all over 2
B:d equals T over 2 minus a minus b minus c
C:d equals T plus a plus b plus c all over 2
D: d = 2(T − a − b − c)
