Step-by-step explanation:
The rounding process Roxy is using is c)Rounding to the Nearest Whole Dollar.
When rounding to the nearest whole dollar, the decimal part of a number is dropped and the whole number is increased or decreased depending on the value of the dropped decimal. If the dropped decimal is 0.5 or greater, the whole number is rounded up. If the dropped decimal is less than 0.5, the whole number is rounded down.
For example, if Roxy spent $12.50 on an expense, it would be rounded to $13 because 0.5 is greater than 0. If Roxy spent $6.30 on another expense, it would be rounded to $6 because 0.3 is less than 0.5.
