For which of the situations would estimating be the appropriate method of calculation?
a) calculating your tax return.
b) a teacher calculating your grade.
c) you are paying for a movie ticket.
d) joey has $20 and wants to know if he has enough money to go the movies and get popcorn and a drink.

D. Because if you estimate on your taxes it would cause a lot of problems. estimating on a grade could get you a failing grade even if you passed. And estimating on a price would mean you might pay more than you have to... But estimating on if you have enough money is ok like adding all the dollars and not the cents totally fine :) I really hope this helps and isn't confusing:)
