Answers
Answer:
Step-by-step explanation:
To find out how much revenue was earned per minute we can divide the total revenue by the number of minutes.
When numbers are in scientific notation, we can divide in two separate steps. First, let's divide the powers of ten, then we'll divide the other numbers.
Because of the properties of exponents, we can subtract the exponent in the denominator from the exponent in the numerator to divide the powers of 10.
Now we can divide the numbers that are not powers of 10.
The problem asks us to round to two decimal places, so our final answer will have three digits including the ones place. Let's round
so the final answer will have three digits.
Now let's put the two results back together.
How can we rewrite this number in scientific notation?
The movie earned $1.21×10^7 in revenue per minute.
