Step-by-step explanation:

Use nCk for this. 16C5. This is $\frac{n!}{(n-k)!(k!)}$ . This becomes $\frac{16!}{(11!)(5!)}$ . This is $\frac{16*15*14*13*12}{5*4*3*2*1}$ due to 16! and 5! canceling out. This becomes 4368.

C. 1 day

Step-by-step explanation:

Chris:

10 - 4d

Evan:

8 - 2d

How many days will it take before they both have the same number of bags remaining?

Equate both expressions and solve

10 - 4d = 8 - 2d

Collect like terms

10 - 8 = -2d + 4d

2 = 2d

Divide both sides by 2

d = 2/2

= 1

d = 1 day

It will take 1 day before they both have the same number of bags remaining
