The rate of change of the area covered by a mold on a piece of bread is $\boxed{0.67}.$

Further explanation:

The rate of change can be expressed as follows,

Given:

Nine days ago the area covered by a mold on a piece of bread was 3 square inches.

Today the mold covers 9 square inches.

Explanation:

The final area covered by a mold on a piece of bread is $9{\text{ square inches}}.$

The initial area covered by a mold on a piece of bread is $3{\text{ square inches}}.$

Initial time is 0.

Final time is 9.

The rate of change can be calculated as follows,

$\begin{aligned}{\text{Rate of change}}&= \frac{{{\text{Final value}} - {\text{Initial value}}}}{{{\text{Final time}} - {\text{Initial time}}}}\\&=\frac{{9 - 3}}{{9 - 0}}\\&= \frac{6}{9}\\&= \frac{2}{3}\\&= 0.67\\\end{aligned}$

The rate of change of the area covered by a mold on a piece of bread is $\boxed{0.67}.$
