DVD players are going out of fashion in the modern era. If 400,000 DVD players were sold this year and sales are declining at a rate of 31% per year, how many will be sold 3 years from now?
130,000
131,404
128,000
399,876
400,000 * (1 - 0.31)^3
To find out how many DVD players will be sold 3 years from now, we need to calculate the sales decline for each year and subtract it from the previous year's sales.
The formula to calculate the sales decline is:
Sales in a specific year = Sales in the previous year - (Sales in the previous year * Decline rate)
Let's apply this formula to calculate the sales for each year:
Year 1:
Sales = 400,000
Year 2:
Sales = 400,000 - (400,000 * 0.31)
Sales = 400,000 - 124,000
Sales = 276,000
Year 3:
Sales = 276,000 - (276,000 * 0.31)
Sales = 276,000 - 85,560
Sales ≈ 190,440
Therefore, approximately 190,440 DVD players will be sold 3 years from now.
The closest option to this is 191,000, so none of the given options matches exactly.
