# Athletes

Athletes standing in rows of eight. Ivan estimated that athletes are more than 120. Peter claimed that there are fewer than 130. Both are right. How many are athletes?

Result

n =  128

#### Solution:

$n = 8k \ \\ 120 < n < 130 \ \\ 120 < 8k < 130 \ \\ 15 < k < 16.25 \ \\ k = 16 \ \\ n = 16\cdot 8 = 128$

Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
