Question

A local radio station had a contest to see who could guess closest to the actual number of jellybeans that filled a small car. the number of jellybeans that were in the car was 785,000. the radio station used bags that contained 800 jellybeans each and dumped the jellybeans in the car until is was full. randall and susie had an argument about how many bags the radio station had to use to fill the car. randall claimed the radio station needed more than 981 bags. susie claimed that the radio station used exactly 981 bags to fill the car. who is correct? explain by finding exactly how many bags of jellybeans the radio station used to fill the car.

Answer 1

Given:
Number of jelly beens in the car: 785,000
Number of jelly beans in a bag: 800

Number of bags needed to fill the car?

785,000 / 800 = 981.25

Randall claimed = more than 981 bags
Susie claimed = exactly 981 bags.

Randall is correct. More than 981 bags.

981 x 800 = 784,800  

There is a missing 200 jelly beans if exactly 981 bags were used. Thus, a quarter of the 982nd bag is used to complete the 785,000 jelly beans.
