Answer:
Highest score is 21.5
Step-by-step explanation:
Let the highest score be h
Let the lowest score be l
Therefore
h = 3l - 4 (1)
and
h - l = 30 (2)
I. E.
h = 30 - l (3)
Substituting (3) in (1)
30 - l = 3l - 4
Collecting like terms
30 + 4 = 3l + l
34 = 4l
l = 34/4
l = 8.5
Then substitute l = 8.5 in (1)
h = 3l - 4
h = 3(8.5) - 4
h = 25.5 - 4
h = 21.5
