Answer: 1,356 tickets
12x=16,272
divide by 12 on both sides
12x÷12=16,272÷12

x=1,356
I hope this is good enough:
The formula for N choose K is given as:
C(n, k)= ![\frac{n!}{[k!(n-k)!] }](https://tex.z-dn.net/?f=%20%5Cfrac%7Bn%21%7D%7B%5Bk%21%28n-k%29%21%5D%20%20%7D)
Where,
n is the total numbers.
k is the number of the selected item.
Options C is correct.
Answer:
The call lasted 13 minutes
Step-by-step explanation:
In this question, we are told to find the number of minutes a call lasted.
The initial amount on the card is $30 and after making a phone call just once, the balance went down to $28.83
What was used would be 30 - 28.83 = $1.17 or simply 117 cents
Now these long calls come at a cost of 9 cents per minute and we have a total of 117 cents here; the number of minutes is thus 117/9 = 13
This means Kala spent 13 minutes on the call
