Questions: Determine the percent decrease in box office earnings from 2016 to 2017. The earnings decreased by %.

Solution Steps

To determine the percent decrease in box office earnings from 2016 to 2017, we need to follow these steps:

1. Calculate the difference in earnings between 2016 and 2017.
2. Divide the difference by the earnings in 2016 to find the decrease as a fraction of the 2016 earnings.
3. Multiply the result by 100 to convert it to a percentage.
4. Round the result to the nearest tenth.

The earnings in 2016 were \$1000 and in 2017 were \$800. The difference in earnings is: \[ \text{difference} = 1000 - 800 = 200 \]

To find the percent decrease, we divide the difference by the earnings in 2016 and multiply by 100: \[ \text{percent decrease} = \left( \frac{200}{1000} \right) \times 100 = 20.0 \]

The percent decrease is already at one decimal place, so no further rounding is needed.
