Exactly what you said...
<span>a = 1, b = 4, c = - 21
a = 1, b = 4, c = 21
a = 0, b = 4, c = - 21
a = 0, b = 4, c = 21</span>
You turn 85% into a decimal
then multiply the decimal by the main number.
420x.85=357.
so 85% of 420 is 357
Simple interest rate for one year = 1.5%
simple interest rate over 5 years = 1.5 x 5 = 7.5%
100% + 7.5% = 107.5%
107.5% = $19500
1% = 181.3953
100% = $18140.50
He needs to put in $18140.50 so that he can get $19,500 at the end of 5 years.
Answer: OPTION B
