of the task , we know that :

profit netto = $ 6100
influenza students = 7
hourly rate for one lesson of the French language  = $45

we do not know about

profit brutto = ?    denoted as x

the amount collected lessons
for one student = ?    denoted as y

x = $6100 + $200
[tex] y = \frac{x}{45*7} [/tex]

[tex] \left \{ {{x=6300} \atop {y= \frac{6300}{315} =2}} \right. [/tex]

2 away

[tex]y = \frac{6100 + 200}{45 * 7} = 2[/tex]
