x represents the total sales and y represents the total amount of money that Gary earns.
Gary's monthly salary = 1500
His commission = 10% of his sales
= 
= 0.1x
So, total amount of money Gary earns is y = 0.1x + 1500.
By rounding 842 to 800, she can multiply 800 by 3 to get 2,400.
then, multiply 40 by 3, you get 120 and add the two together to get 2,520
this shows her answer is not necessary reasonable
