Given:
The fees for a day student are $600 a term.
The fees for a boarding student are $1200 a term.
The school needs at least $720000 a term.
To show:
That the given information can be written as 
.
Solution:
Let x be the number of day students and y be the number of boarding students.
The fees for a day student are 
a term.
So, the fees for 
day students are 
a term.
The fees for a boarding student are 
a term.
The fees for 
boarding student are 
a term.
Total fees for day students and boarding student is:
The school needs at least $720000 a term. It means, total fees must be greater than or equal to $720000.
Divide both sides by 600.
Hence proved.
