First let's find how much is 15% of 8500 voters.
To do that, we can multiply 15 by 8500 and then divide by 100.
Work: 15 x 8500 = 127500
127500/100 = 1275
Therefore 15 percent of 8500 is 1275.
Then, we subtract 1275 from 8500 to find the amount of people who did vote.
8500 - 1275 = 7,225
Thus, 7,225 people voted while 1,275 people did not.
If it take some x minutes to upload some y digital photographs, it means it has an average of: x/y minutes to upload a single digital photograph. Then, to upload z photographs, you just multiply x/y by z.
Spoilers for answer:
