[tex]\$ \square[/tex]



Answer :

To determine how much revenue was earned per minute of the animated movie, we will follow these steps:

1. Identify the given values:

- Total revenue earned by the movie: [tex]\(\$ 1.1 \cdot 10^9\)[/tex]
- Duration of the movie: [tex]\(9.1 \cdot 10^1\)[/tex] minutes

2. Convert these values into standard form:

- Total revenue: [tex]\(\$ 1,100,000,000\)[/tex]
- Duration: [tex]\(91\)[/tex] minutes

3. Calculate the revenue earned per minute:

[tex]\[ \text{Revenue per minute} = \frac{\text{Total revenue}}{\text{Duration in minutes}} \][/tex]

Substituting the given values:

[tex]\[ \text{Revenue per minute} = \frac{1,100,000,000}{91} \approx 12,087,912.087912088 \][/tex]

4. Round the result to two decimal places:

[tex]\[ 12,087,912.087912088 \approx 12,087,912.09 \][/tex]

5. Express the rounded result in scientific notation:

- The number 12,087,912.09 in scientific notation is written as [tex]\(1.21 \cdot 10^7\)[/tex]

So, the revenue earned per minute of the movie is:

[tex]\[ \boxed{\$ 1.21 \cdot 10^7} \][/tex]
