## Question

On Sunday \(845 \) people went to the zoo. On Monday only \(169\) people went. What is the per cent decrease in the people visiting the zoo on Monday?

## 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

**Reasoning:**

Finding the decrease in number of people and calculating it for \(100\), will get us the percentage decrease.

**Steps:**

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 \(= 80\%\)
