Answer:
(A) $157.25
(B) $3,857.25
Step-by-step explanation:
The given values are:
Principle (P)
= $3700
Time (T)
= 6 months i.e., 1/2 years
Rate (R)
= 8.5%
(A)
As we know,
Simple Interest,
⇒ [tex]SI=\frac{P\times R\times T}{100}[/tex]
On putting the values, we get
⇒ [tex]=\frac{3700\times 8.5\times \frac{1}{2} }{100}[/tex]
⇒ [tex]=\frac{15,725}{100}[/tex]
⇒ [tex]=157.25[/tex] ($) (he paid for the use of money)
(B)
Amount he paid to the bank will be:
⇒ [tex]P+SI[/tex]
⇒ [tex]3700+157.25[/tex]
⇒ [tex]3,857.25[/tex] ($)
