Answer:
Step-by-step explanation:
Let the number of students be x
<u>Initial share was:</u>
<u>With the less students the share is:</u>
- 120 /(x - 8) = 120/x + 0.5
<u>Solve for x:</u>
- 120 /(x - 8) = 120/x + 0.5
- 120x = 120(x - 8) + 0.5x(x - 8)
- 120x = 120x - 960 + 0.5x² - 4x
- 0.5x² - 4x - 960 = 0
- x² - 8x - 1920 = 0
- x² - 8x + 16 = 1936
- (x - 8)² = 1936
- x - 8 = √1936
- x - 8 = 44
- x = 52

This question is a little ambiguously worded, however I assume the answer would simply be:
$500 - $112 - $28 = the amount he has left.
Hope this helped :))
