Answer 1

Solution.

1) The formula for calculating the value of investment:

$$B=A(1+\frac{p}{100})^n,$$

where $B$ is the future value;

$A$ - current value;

$p$ - interest rate for the settlement period (day, month, year, ...);

$n$ is the number of settlement periods.

Сalculate the amount after 17 months:

$B=7,500(1+\frac{3.6}{100})^{\frac{17}{12}}=\newline 7,500*1.036^{\frac{17}{12}}=7,885.35$$

Answer. e None of these

2) The formula for calculating the value of the note:

$$P=S(1-\frac{d}{m})^{m\cdot n},$$

where $P$ is the value of the note;

$S$ - face value;

$d$ - interest rate for the settlement period (day, month, year, ...);

$m$ is number of charges per year.

$P=950(1-\frac{0.08}{4})^{4\cdot 3.5}=715.96$ $

Discount of this note $S-P=950-715.96=234.04$ $

Answer. e None of these
