Find the differences:
3-0 = 3
9-3 = 6
18-9 = 9
The differences increase by the previous difference plus 3
So 5 kids would have 9+3 = 12 + 18 = 30 interactions.
6 kids: 30-18 = 12 +3 = 15 + 30 = 45 interactions.
7 kids: 15+3 = 18 + 45 = 63 interactions.
8 kids: 18 +3 = 21 + 63 = 84 interactions.
9 kids: 21+3 = 24 + 84 = 108 interactions.
The answer is d. 108

A nice trick i use for word problems is that i highlight the numbers and what they are, like: liters, kilograms, grams, etc. say this is your word probem:
Suzie made <u>30 kilograms</u> of party mix chips and <u>40 liters of punch</u> for her party, Suzie had <u>20 people at her party</u>, how much punch and party mix chips will there be when the party is over?
I highlighted what i would have highlighted if it was a real word problem.
Good luck! Hope my trick works for you too!
The formula is
A=p (1+rt)
A future value 1249.22
P present value ?
R interest rate 0.14
T time 1 year
We need to solve for p
P=A÷(1+rt)
P=1,249.22÷(1+0.14×1)
P=1,095.81 round your answer
P=1096
