Answer:
x = 159; y = 140
Step-by-step explanation:
a = 40
a + y = 180
y = 180 - 40
y = 140
b = 61
b = (180 - x) + a
61 = 180 - x + 40
x = 159
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.

Answer:
20(7 + 10)
Step-by-step explanation:
The GCF of 200 and 140 are 20
.: by GCF and factoring we have:
20(7 + 10)
Opening the bracket still gives the initial expression.
