A carpenter makes 4 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? Options: A) 3. B) 4. C) 5. D) 6. E) 7.
I believe it is C because if 1C makes 3 beds in 1 day then:   1C's rate = 3/1   So 5c's = 3/1 * 5=

15 beds in a day.   Since we have 173 soldiers who need beds and bunk beds come in pairs, 72 is the least amount of beds needed.   Time= Amount / Rate   Time = 72 / (15/1) = 72/15, simplifying we get 72/15 = 24/5 = 4.7   So, in order for the carpenters to be able to finish they need 5 whole days. At first I made the mistake of thinking how many whole days it took them to finish (as in ignore the partial day) but the prompt clarifiesdays in advance, meaning how many days would they need to finish so even if they finish early, theyusedthat day.   5.
