CD players are going out of fashion in the modern era. If 400,000 CD players were sold this year and sales are declining at a rate of 17% per year, how many will be sold 3 years from now?

400000 * (0.83)^3

Step-by-step explanation:

A yearly decline of 17% means the number sold is getting MULTIPLIED by (1-17%) = (100%-17%) = 83% = 0.83. The number sold 3 years from now will be

400000 * (0.83)^3

228715 CD

Step-by-step explanation:

In the first year the sale would be ;

100-17 / 100 × 400,000= 83/100 × 400,000 = 332000 CD.

In the second year the sale would be;

83/100 × 332000 CD= 275560CD

In the third year the sale would be;

83/100 × 275560CD = 228714 .8 CD

It's approximated to the nearest whole.
