directrix · Answer

The problem about getting the mean, median, and mode is not for the camera prices in the store but for the prices of the cameras after 6% sales tax has been added.

So, each camera store cost had to be multiplied by 1.06 to get the cost after sales tax.

Then, those after tax costs had to be used to find, the mean, median, and mode.

anonymous · Answer

these are the answer choices I have
mean = $318.00
median = $339.20
mode = $445.20
range = $21.20

mean = $339.20
median = $318.00
mode = $445.20
range = $243.80

mean = $339.20
median = $318.00
mode = $445.20
range = $21.20

mean = $445.20
median = $318.00
mode = 339.20
range = 243.80

6% = 0.06

directrix · Answer

That would give only the sales tax.
1.06 as a multiplier gives the camera cost plus the tax all in one number.

Let me look for what went wrong.

directrix · Answer

Mean: (201.4 + 445.20 + 286.20 + 318 + 445.2)/5= 339.20

directrix · Answer

That is better.

thank you sorry had to take care of the animals

directrix · Answer

Median is 318

anonymous · Answer

what would the range be?

directrix · Answer

Range is 445,20 - 201.40 =243.80

directrix · Answer

mean = $339.20
 median = $318.00
 mode = $445.20 
range = $243.80

I think.
