Over the summer, Jackie played video games 3 hours per day. When school began in the fall, she was only allowed to play video games for half an hour per day What is the percent decrease? Round to the nearest percent.

Respuesta :

In order to solve percent of change problems you can use the following formula:
(( |Data2-Data1| ) / Data1)*100= % Change
with Data 1 being the original data (in your case, 3 hours)
and Data 2 being the second set of data (.5 hours in your case)

Using this as
((|.5-3|)/3)*100
we can evaluate the % change to be an 83.33% decrease in her gaming time.

Hope this helps to keep your parents from decreasing your game time!

Jackie played video games 3 hours per day. When school began in the fall, she was only allowed to play video games for half an hour per day then the percent decrease is 83%.

Given :

  • Over the summer, Jackie played video games 3 hours per day.
  • When school began in the fall, she was only allowed to play video games for half an hour per day.

The unitary method can be used to determine the percentage decrease. Given that over the summer, Jackie played video games 3 hours per day which means 3 hours is 100% she can not play video games more than that.

So, if she plays half an hour per day then:

[tex]= \dfrac{0.5}{3}\times 100[/tex]

= 16.67% [tex]\aaprox[/tex][tex]\approx[/tex] 17%

Therefore, the percentage decrease is given by:

= 100 - 17%

= 83%
