Question

The change in the value of an account when given to the nearest dollar

Answer 1

What changes may occur if the given dollar will be rounded off to its nearest value.
There will only be 2 chances, the dollar will become smaller or bigger. Why?
Because in mathematical rules of rounding off numbers:
number below 5 will be round down and 5 and up will be rounded up.
For example:
You have a bill of $6.79  since the number next to the decimal point in the right is 7, it will be rounded up to $7.
But if your bill is $6.25, it will be rounded down to $6.00
