Choose the situation in which the use of approximate numbers is most appropriate.
A) A contractor is ordering gravel to spread in a driveway.
B) A band director is ordering batons for the majorette squad.
C) A builder is ordering windows to install in a home he is building.
D) The director of purchasing is buying police cars for the officers in a police force.
Getting an exact number for gravel is difficult because it spills and the ground is not usually perfectly level. Thus it would be okay to estimate the amount needed.
