Lady bird [3.3K]
We can first find the number of different types of candy he got:

The number of sugar candy he got:

34×8
=272

The number of chocolate candy he got:

What value of n solves the equation <br><br> 3n=1/81<br><br> N=___
Radda [10]

3n = 1/81; divide both sides by 3 to isolate n:


3n/3 = 1/81 divided by 3. Remember that when you divide, you use the reciprocal and multiply instead!!


n = 1/81(1/3) = 1/243. Now plug 1/243 back in for n, and 3/243 is equivalent to 1/81
