CB 4000 at 5%, how much is that? (5/100) * 4000

part B)

total investment was 12000 + 4000 = 16000

the earned interest above are 720 and 200 respectively

total yield was, 720 + 200 = 920

if 16000 is the 100%, how much is 920 in percentage?

$\bf \begin{array}{ccllll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
16000&100\\
920&x

solve for "x"
