Hey! I'll provide you the answers!
First you want to simplify the equation using cross-multiplication.

Finally, you would want to divide both sides by 15.
n = 161
Answer:
0.375%
Step-by-step explanation:
i=P*R*T
$360=$8000*R/100*18/12
$360=$960R
$360/$960=$960/960
0.375%=R
Divide 1515 by 100 and you would get 15.15 the divide the .15 by 3 and and you will get 3.5 so the answer will be 15 3/5
Ok. Because there are 6 people and 8 pieces. So 6 people have 1 slice each. The other 2 pieces.
The other 2 pieces have to divide both pieces into 3 hat way everyone has a pieces
Every one will have 1 1/3 pieces.
