Answer:
5x+2y=13
Step-by-step explanation:
3x+3y=8
2x-y=5
5x+2y=13
We want to list the steps involved in multiplying fractions;
Taking an example;
First steps are;
- Multiply the numerators together
- Multiply the Denominators together
Next is to;
Check to see if the product can be simplified;
So, we get the product to be;
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.
