$p = 150500$ , $t = \frac{2}{3}$ , $r = 0.085$

Step 1

Simple interest is calculated on the original principal only. Accumulated interest from prior periods is not used in calculations for the following periods.

$i = p \cdot r \cdot t$

Step 2

Solve the equation for $i$ .

Step 2.1

Remove parentheses.

$i = p \cdot r \cdot t$

Step 2.2

Multiply $p r$ by $t$ .

$i = p r t$

Step 3

Substitute the known values into the formula.

$i = (150500) \cdot ((0.085) (\frac{2}{3}))$

Tap for more steps...

Step 4.1.1.1

Combine $0.085$ and $\frac{2}{3}$ .

$i = 150500 \cdot \frac{0.085 \cdot 2}{3}$

Step 4.1.1.2

Multiply $0.085$ by $2$ .

$i = 150500 \cdot \frac{0.17}{3}$

Step 4.1.2

Divide $0.17$ by $3$ .

$i = 150500 \cdot 0.05\overline{6}$

Step 4.1.3

Multiply $150500$ by $0.05\overline{6}$ .

$i = 8528.\overline{3}$
