Answer:
5 servers and 3 cooks(since a person doesn't exist in fraction)
Step-by-step explanation:
From the question provided above, the manager(who is obviously organizing some kind of party or get-togethers) is expecting a hindered and fifty guests in total .
And it also says that if a server can handle 30 guests and 150,how many of them are need?
Let X be number of servers needed:
X= 150/30 = 5 servers
AND
If a single cook can prepare meals for 60 guests,the number of cooks required to cover for 150 guest will be:
X= 150/60 = 2.5,but since a fraction of a human doesn't exist, we have to say that the manager needs 3 cooks(2 of them will handle a total of 120 guests and the other cook handles the 30 guests)
