A ship must have 1 lifeboat for every 12 passengers, plus one lifeboat for the crew and one backup lifeboat. Which equation shows the relationship between the number of passengers, p, and the number of lifeboats needed, l ?

Select one:


l=2+ l/12


l=2p+10


l=12p


l=2+p/12

Answers

Answer 1
72/12=p=6. C=1*12
The explanation is that if there are 72 passengers u would divide by 12 to equal 6 then just one boat for crew so the maximum of 12 crewmates
