Answer:
Approximately

Step-by-step explanation:
Explanation:
We are trying to determine the value of
h
in the compound growth formula
XXX
20
×
(
1
+
0.85
)
h
=
2000
or, simplified:
XXX
1.85
h
=
100
Taking the
log
1.85
of both sides:
XXX
log
1.85
100
With the aid of my trusty spreadsheet:
XXX
h
≈
7.48582192
I believe the answer is ten pairs...
The two rows each have 3 pairs touching, and the four columns each have 1, which makes 2*3 + 4*1 = 10
7/8 -1/4
= 7/8 -2/8
= 5/8
The final answer is 5/8~
