Combinations
nCr
n (objects) = 9
r (sample) = 3
9C3
n! / r! (n – r)!
9! / 3! (9 – 3)!=
9! / (3! * 6!)=
9*8*7*6!/ (3! * 6!)=
6! cancels out
9*8*7/3*2*1=
3*4*7=
12*7=

Answer:
24 multi-scented candles
10 single-scented candles
Step-by-step explanation:
There was no question, so I am going to assume that you want to know how many of each type of candles were sold.
Let m = no. of multi-scented candles
s = no. of single-scented candles
(1) m + s = 34 (2) 3m + 2s = 92
s = 34 - m 3m + 2(34 - m) = 92
3m + 68 - 2m = 92
m + 68 = 92
m = 24
s = 34 - 24 = 10
