Question

Sales of video games and consoles fell from \(1,150 million to \)1,030 million in 1 year. Find the percent decrease. (Round to the nearest tenth of a percent.)

Short answer

The percent decrease in the sales will be 10.4% in a year.

Step-by-step solution

Step. 1 Given Information

The sales of video games and consoles was $1,150 million one year ago.

And now the sales of video games and consoles is $1,030 million only.

Step. 2 Percentage calculation

The change in the sales in the past one year is: $1,150 - $1,030 = $120 million

Now, the percent change in the sales will be calculated as follows:

$$\begin{gathered} =\frac{Changeinthesalesinoneyear}{Totalsalesoneyearago}\times 100\% \\ =\frac{-120million}{1,150million}\times 100\% \\ =-0.104347...\times 100\% \\ =-10.4347....\% \\ =-10.4\%(Roundingofftotenthplace). \end{gathered}$$

This negative sign shows that the change is negative and it is percent decrease.

Therefore, 10.4% will be the percent decrease.
