There are 12 employees at the sub shop. How many ways can the manager choose 4 for the Sunday evening shift? Permutation or combination and the answer?

It is a combination answer

495 ways

Step-by-step explanation:

In this question, we are tasked with calculating the number of ways in which a manager can select 4 people out of 12 for the Sunday evening shift.

Firstly, the question talks about selecting a particular number from a mix, this is a combination question since the key word SELECT is mentioned.

Now, how do we go about it? To select a partial number from a mix , we use the combination formula as stated.

Mathematically, say we are selecting a number r from a total of numbers n, the number of ways we can do this is nCr = n!/(n-r)!r!

In this case however, we are simply selecting 4 out of 12

Our combinational equation thus becomes 12C4 = 12!/(12-4)!4! = 12!/8!4! = 495 ways

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
