Answer:
Step-by-step explanation:
Mr. Chan originally placed 4,000 in the bank as a fixed deposit for 2 years.
Each years the bank added a certain amount of interest.
At the end of the 2 years he gained 243 dollars and 60 cents just from interest.
How to solve:
Simply take away the 4 in the amount of money
Leaving: $243.60
( 2 years )
Now divide 243.60 by 1/2
which is 121.8
Mr.Chan got 121.8 worth of interest a year
$10.5 a month
$2.3 a week
6 cents a day
All in 2 years.
b=5, commutative property
c=3, associative property
All are easy. There is no way to say thatnone way is easier than the other. Well the answer lies in every individual, it depends on which method they are comfortable with. Anyway there are more method to solve quadratic than the listed ones.
Answer:

Step-by-step explanation:
Multiply -5 by each term inside the parentheses.



189000/x=100/4.5
<span>(189000/x)*x=(100/4.5)*x</span>
<span>189000/22.2222=x </span>
<span>8505=x </span>
