Answer 1

The principal amount is

`P=3000`

The time for which money is borrowed is,

`t=9\text{ months}`

The interest rate is,

`r=3(1)/(2)`

Determine the time in terms of year by divison of time by 12.

`\begin{gathered} t=(9)/(12)\text{ years} \\ =(3)/(4)\text{ years.} \end{gathered}`

The formula for the intrest is,

`I=(P\cdot r\cdot t)/(100)`

Substitute the known calues in the formula to obtain the value of interest.

`\begin{gathered} I=(3000\cdot(3)/(4)\cdot3(1)/(2))/(100) \\ =(3000\cdot3\cdot7)/(2\cdot4\cdot100) \\ =78.75 \end{gathered}`

So intrest paid by the woman is $78.75.

(b)

Determine the amount paid by the woman.

`\begin{gathered} A=P+I \\ =3000+78.75 \\ =3078.75 \end{gathered}`

So woman repay $3078.75 to the bank.
