for 2 years How much total amount she received at the end of the
period ?
​

Answer 1

Answer:

AMOUNT DEPOSITED = $1700

RATE = 9% p.a.

TIME= 2 yrs

FROM THE FORMULA,

$si = ptr \div 100$

$so \\ si = 1700 \times 2 \times 9 \div 100 \\ = 30600 \div 100 \\ = 306$

THEREFORE,

SIMPLE INTEREST =$306

$now \\ amount = \times \: compound \: interest + principal \\ = 1700 + 306 \\ = 2006$
