Question

Max lives 37 mi from his grandmother. What is the range of values this measurement represents?

Answer 1

Depends on the rounding rule that you use.

Rule: round up on a 5 means that anything equal to or greater than 36.5 would round up to 37 and anything less than 37.5 would round down to 37.

Answer 2

Rule: Round a 5 to the nearest even number would mean that anything greater than 36.5 would round up to 37 and anything less than 37.5 would round down to 37.

Answer 3

So the range is either one of the following:

36.5 <= x < 37.5
36.5 < x < 37.5
