J = 106% . x
S = 106% . (550+x)
O = 106% . 2x

S = 2(212+O) = 106%(550+x)
S = 424 + 2O = 583 + 106%x
2(106%.2x) - 106%x = 583-424
159 = 106%x( 4 - 1 )
159 = 106%x ( 3 )
159 = 318%x
1 = 318%x : 159
1 = 2%x
1 = 2/100 . x
x = 50

Jivesh put $50
Stacy put $600
Oliver put $100

How many subsets are there in {1, 2, 3, 4, 5, 6}?
Contact [7]
<h3>Answer:  64</h3>

Explanation:

If there are n = 6 items in the set, then there are 2^n = 2^6 = 64 subsets

This is because there are 2 choices per slot. Either the item is in the subset or not. Since we have 6 slots, and 2 choices per slot, we have (2*2*2)*(2*2*2) = 2^6 = 64 different combos.

Side note: The empty set is included as one of the subsets. Also, the original set itself is a subset.
