## Text Solution

What is known?

Number of people visited zoo on Sunday $$= 845$$

Number of people visited zoo on Monday $$= 169$$

What is unknown?

Percent decrease in the people visiting zoo on Monday

Decrease in the number of people $$= 845-169 = 676$$

Percentage decrease in the number of people

\begin{align}&= \frac{{{676}}}{{{845}}}{ \times 100}\\ &= 4 \times 20\\ &= 80\% \end{align}

Percentage decrease in the people visiting zoo on Monday $$= 80\%$$
