Let's define variables:
 x = number of times he threw 50 free throws per day.
 y = number of times he threw 100 free throws per day.
 We write the system of equations that adapts to the problem:
 x + y = 20
 50x + 100y = 1250
 The solution to the system is:
 x = 15
 y = 5

 Answer:
 Mark did shoot 100 free throws for the day about:
 y = 5 times.
