⇒  P[(X

By putting the values, we get

                                     =\frac{[P(2)+P(3)]}{[1-P(0)-P(1)]}

                                     =\frac{(0.20+0.15)}{1-0.20-0.30}

                                     =\frac{0.35}{0.5}

                                     =0.70

Tpy6a [65]

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,

⇒  SI=\frac{P\times R\times T}{100}

On putting the values, we get

⇒       =\frac{3700\times 8.5\times \frac{1}{2} }{100}

⇒       =\frac{15,725}{100}

⇒       =157.25 ($) (he paid for the use of money)

(B)

Amount he paid to the bank will be:

⇒  P+SI

⇒  3700+157.25

⇒  3,857.25 ($)
