Answer:
8
Step-by-step explanation:
The question is on number of subsets
Number of subset is given by 2^n
n=3 in our question, A,B,C
2^n = 2^3 =8
They are; { }, A, B, C, AB, AC, BC, ABC
$3.36 divided by 12 cookies is $0.28 per cookie.
18/24 = 0.75
0.75 x 100 = 75%
First, divide each amount by the downloads.
6.25/5 = 1.25 for each download
17.40/12 = 1.45 for each download
The online music store that offers 5 downloads for 6.25 is the better deal by 0.20 cents.
hope this helps
