Total = $6,120 #### Explanation: Use the formula $P r t = i \text{ }$where $P = \text{ principle} \left(6000\right)$$r = \text{ rate}$- as a decimal $\left(0.08\right)$, $t = \text{ time in years } \left(\frac{3}{12} \mathmr{and} \frac{1}{4}\right)$$i = \text{ interest earned }$$P r t = i \text{ } 6000 \cdot 0.08 \cdot 0.25 = i$i=$120

For the total, add on the $6,000 Jul 28, 2017 Total Amount = $6000+$120 =$6,120

#### Explanation:

You can work with the % as being over $100$

$S I = \frac{P R T}{100}$

Note that the time, $\left(T\right)$, is given as years.
Dividing months by $12$ indicates years: $3$ months =$\frac{3}{12}$ years

$S I = \frac{6000 \times 8 \times 3}{\text{ } 100 \times 12}$

Easy cancelling gives the following:

$S I = \frac{{\cancel{60}}^{5} \cancel{00} \times 8 \times 3}{\cancel{100} \times \cancel{12}}$

SI = $120 For the total amount we have to include the original $6,000 as well.

Total Amount = $6000+$120 = \$6,120
