Root 37 is closer to 6, since root 36 is 6.
Sorry, misunderstood question, answer beneath me much better.
In the terms it’s none of them because this is way to confusing
If the first number behind the decimal point is lower than five, you leave the digits in front of the decimal the same. If it is equal to or above five, then the number in front of the decimal is rounded up. In this case it would stay the same, so your answer would be 585.
For this you can just use a calculator and divide 2587.5 by 1150.
You should get $2.25 for the unit price. Hope this helped ^-^
