PLZ HELP WILL GIVE BRAINLIEST!!!!!!
Travka [436]
We should find the mean number of the tests. 
This would be done like: (23+24+25)/3  = 24

After that, you should find the percentage or fraction like this 24/50
Then use the fraction as an estimate like this:

(24/50) * 3250 = 1560

The correct answer is 1560.
