Given that:

• Louise Tammy Dolores and Cheryl score 78 points in the tennis matches they play.

• A score consecutive number of points from smallest to greatest in respect to the order of the names: Louise Tammy Dolores and Cheryl.

Let be:

- The number of points that Louise scored in the tennis matches:


n

- The number of points that Tammy scored in the tennis matches:


n+1

-The number of points that Dolores scored in the tennis matches:


n+2

- The number of points that Cheryl scored in the tennis matches:


n+3

You can set up the following equation to represent the total number of points they scored in the tennis matches:


n+(n+1)+(n+2)+(n+3)=78

Now you can solve for "n":


n+n+1+n+2+n+3=78
4n+6=78
4n=78-6
\begin{gathered} n=(72)/(4) \\ \\ n=18 \end{gathered}

Hence, the answer is: Option D.
