trasher [3.6K]

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
