Question

the largest soccer and football stadiums have a capacity of at least 1x10⁵ people. Each stadium has 8 events each year for 10 years. How many total people attend these events if every event was seated to capacity?

Answer 1

The first step to solve this problem is to calculate the total number of events for these 10 years. Each year there's 8 events, so to find the total number of events we need to multiply the total number of years by the number of events per year.

`\text{events}=8\cdot10=80\text{ events}`

There will be 80 events in these 10 years. Each event can receive 1x10⁵ people, to find the total number of people that will attend these events we need to multiply the number of events by the number of people who will attend to each event. We have:

`\begin{gathered} \text{total people}=80\cdot1\cdot10^5 \\ \text{total people}=80\cdot10^5=8,000,000\text{ people} \end{gathered}`

At least 8,000,000 people will be able to attend the events. In scientific notation this is:

`\text{total people}=8\cdot10^6\text{ people}`

The total number of people will be 8*10^6
