In a class, the highest score is 91. If the highest score is twice thelowest score plus 11, find the lowest score.​

Answer»

Answer:

The lowest score of the exam was 40.

Step-by-step explanation:

It is PROVIDED that the highest score is twice the  lowest score PLUS 11.

The STATEMENT can be expressed as follows:

      Highest score = (2 × Lowest score) + 11

                          91 = (2 × Lowest score) + 11

(2 × Lowest score) = 91 - 11

       Lowest score = 80/2

                               = 40

Thus, the lowest score of the exam was 40.
