Answer:
Step-by-step explanation:
Denote x is the hour you work as a cashier per week; y is the hour you mow lawns per week.
You would like to work no more the 10 hours per week, meaning that : x + y <= 10 or y <= -x +10 (a);
You would like to earn at least $50 per week. As we have the total amount you earn per week would be 5x + 10y in which 5x is the amount you get paid as cashier and 10y is the amount you get paid as mowing lawn; we have the inequalities: 5x + 10y >= 50 <=> 10y>= -5x +50 <=> y>= -1/2 x +5 (b) ( as we divided both side of the inequalities by 10)
From (a) and (b) => the second inequalities shown in the picture is the right one
