A carpenter makes 3 bunk beds every day. A military school needs to organize a place to sleep for 143 soldiers. If there are 5 carpenters working on the job, how many whole days in advance should they receive the order and start working in order to finish the right number of beds assuming that each bunk- bed is used by two soldiers?	Choose the correct choice:	A) 3	B) 4	C) 5	D) 6	E) 7
If two soldiers sleep on one bunk bed, school needs 143/2= 72 bunk beds.   1 carpenter can make 3 beds and 5 carpenters can make 15 beds/day.   15 beds will be ready in 1 day, so to have 72 beds ready, carpenters require 72/15 = 5 (closest integer) days   5 is the answer
