Question

Sales of video games and consoles fell from $1.15million to $1.03 million in 1 year. Find the percent decrease. Round the answer to the nearest tenth of a percent. For example, if the answer is 34.08% enter 34.1%.

Answer 1

10.4%

Explanation:

Sales of video games and consoles fell from $1.15 million to $1.03 million in 1 year.

Sales of video games and consoles of last year = $1.15 million

Sales of video games and consoles of this year = $1.03 million

Let the percent decrease = x%

x% =
`(1.15m-1.03m)/(1.15m)`

`(x)/(100)` =
`(0.12m)/(1.15m)`

x = 10.4347% ≈ 10.4%

The decrease percent is 10.4%

Answer 2

we know that

$1.15 million --------> represent the 100% percentage

Find the percentage of $1.03 million

by proportion

100%/1.15=x%/1.03---------> x=1.03*100/1.15

x=89.57%

the percentage decrease is equal to

=100%-89.57%=10.43%--------> Round to the nearest tenth of a percent

=10.4%

therefore

the answer is

the percentage decrease is equal to 10.4%
