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, c and d, and will attend a district match. District match points count for three times 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, b, to advance.

b equals T over 3 minus a minus c minus d
b equals T plus a plus c plus d all over 3
b equals T minus a minus c minus d all over 3
b = 3(T − a − b − d)

The points Tisha and her academic team would need to earn in the district match b to advance is;

Option C; b = (T - a - c - d)/3

Number of points required to go to the state finals = T points

Local matches are; a , c, d

District match; b

Now, district match points are three times the number of points for local matches. Thus district match points will now be 3b

Since they require T points to qualify, if the number of points in each local match are a,b and c, with that of the district being b, then we can say that; a + c + d + 3b = T

To find the number of points they need to obtain in the district match, we will just make b the subject of the formula;

3b = T - a - c - d

b = (T - a - c - d)/3
