Douglas Walker, Vermont's interim commissioner of education, recently accessed the home page of the Union Memorial School in Montpelier and found an invitation from Roger Crowley and his 4th grade students.

The commissioner selected “Wanted: Jack-O-Lantern Carvers.”
Ellie's farm stand advertises 700 carved and lit pumpkins on display Halloween night. To prepare for this event they must carve all the pumpkins in three days (to prevent rotting). They claim that an experienced carver can complete a jack-o-lantern in 10 minutes. How many people must they hire to complete the job within the 3-day limit?
