Answer 2

Calculation of People Visiting the Holiday Home

In August, 1800 people visited the holiday home. In September, the number decreased by 30%, and in October, it decreased by 50%. We need to calculate the number of people who visited the holiday home in October.

Calculation Steps

1. August Visitors: 1800 people 2. September Visitors: 30% less than August 3. October Visitors: 50% less than August

Calculation

1. September Visitors: 1800 - (30% of 1800) = 1800 - (0.3 * 1800) = 1800 - 540 = 1260 people. 2. October Visitors: 1800 - (50% of 1800) = 1800 - (0.5 * 1800) = 1800 - 900 = 900 people.

Therefore, in October, 900 people visited the holiday home.
