It is predicted that sales will

• Decrease by 4.2% in the next year.
• Increase by 5.3% in each of the following 2 years.

Calculate the predicted sales after 3 years.
Give your answer to 3 significant figures.

Answer 1

To calculate the predicted sales after 3 years, we apply the given percentages to the initial sales. We decrease the sales by 4.2% for the first year and increase them by 5.3% for the following 2 years. Finally, we round the result to 3 significant figures.

Step-by-step explanation:

To calculate the predicted sales after 3 years, we need to apply the given percentages to the initial sales. Here are the steps:

1. Decrease the initial sales by 4.2% to find the sales after the first year: 240,000 - (4.2% of 240,000)
2. Increase the sales after the first year by 5.3% twice to find the sales after the second and third years: (sales after first year) + (5.3% of (sales after first year)) + (5.3% of (sales after first year + 5.3% of (sales after first year)))
3. Round the predicted sales after 3 years to 3 significant figures

By following these steps, you will find the predicted sales after 3 years.
