Answer: Age of Lin is 12

Solution:

Let X= age of Maya

(X/2)+4= age of Adrian

((X/2)+4)-7= age of Lin

X+(X/2)+4+((X/2)+4-7)=61

X+.5X+4+.5X+4-7=61

2X+4+4-7=61

2x=61-8+7

2X=60

X=30 age of Maya

19= age of Adrian

Age of Lin is

=((X/2)+4)-7

=15+4-7

=12

h+c=593\\c=h-57

Now we need to solve these two equations to get the value of number of hamburgers. For that we use substitution method as shown below:

h+h-57=593\\2h-57=593\\2h=650\\h=325

Therefore, the number of hamburgers sold on Thursday were 325.
