how many times did maria do
each exercise?

1,147 times

Step-by-step explanation:

15 jumping jacks per set. 25 sets = 25 × 15 = 375

20 sit-ups per set. 20 sets = 20 × 18 = 360

12 push-ups per set. 21 sets = 21 × 12 = 252

10 pull-ups per set. 16 sets = 16 × 10 = 160

375 + 360 + 252 + 160 = 1147
