I believe its the secound to last one

Let's use a for number of days when he shot 50 shots and b for number of days when he shot 100 shots.
We have:
a + b = 20
We also know that he shot total of 1250 shots:
50a + 100 b = 1250
We have two equations. We can solve them for a and b. Let's rearange first equation for a:
a= 20 - b
We insert this into second equation:
50 * (20 - b ) + 100b = 1250
1000 - 50b + 100b = 1250
50b = 250
b = 5
a = 20 - 5
a = 15
Mark shot 100 shots on 5 days.

Answer:
710,000
Step-by-step explanation:
if you are rounding to the nearest 10,000 the only number that matters is the 1,000 number
719,000 rounded to the nearest 10,000 number is 720,000
if the number in the 1,000 place is five or above you round up and if the number is lower than five you round down
