The value of x is
-4x + 8 = 42
-4x = 42 -8
-4x = 34
x = -8,5
Given:
Number of students in the computer training institute = 625 students
Course fee per student = $400
Rate = 50 addt'l students per $20 reduction
Total sales = (625+50x) * ($400-20x)
if reduced by $20, sales = 256500
$40, sales = 261000
$60, sales = 263500
$80, sales = 264000
$100, sales = 262500
The maximum reduction to maximize sales is $80 or $320 per student and 825 students.
