10C4 represent the Combinations of 10 objects taken 4 at a time.
The formula for nCr is:
In the given case, n=10 and r=4. Using these values we get:
This means we can make 210 combinations of 10 objects taken 4 at a time.

Let's write it down:
<span>"60 is 75% of s" means:
60=75%*s
75% is
, (percent just means "out of 100" so we just divide it by 100) so we can also write:
60=</span><span>
s
now, let's multiply both sides by 4:
240=3s
and divide by 3:
80=s
So we have the result that the original value, s, is 80!

Answer:
459 sales people.
Step-by-step explanation
Time per call (t) = 45 min = 0.75 h
Hours per sales person (H) = 3,400 hours
Number of customers (n) = 40,000 customers
Call frequency (f)= 52 calls per year
The total number of sales people (S) needed, is given by the total time spent on calls for the year, divided by the amount of hours each person spends on sale:
Rounding up to the next whole person, Pringles needs 459 sales people.
