Store sells five models of cameras for $190 $420 $270 $300 and $420 if the sales tax rate is 6%, what are the mean median and mode and range of the total cost of the cameras
To calculate the total cost of the cameras after adding the 6% sales tax, we can calculate the amount of tax for each camera model and then add it to the original cost.
Tax for each camera:
- $190 x 6% = $11.40
- $420 x 6% = $25.20
- $270 x 6% = $16.20
- $300 x 6% = $18.00
- $420 x 6% = $25.20
Total cost of cameras after tax:
- $190 + $11.40 = $201.40
- $420 + $25.20 = $445.20
- $270 + $16.20 = $286.20
- $300 + $18.00 = $318.00
- $420 + $25.20 = $445.20
Now we calculate the mean, median, mode and range of these total costs:
Mean = (201.40 + 445.20 + 286.20 + 318.00 + 445.20) / 5 = $339.60
Median = $318.00
Mode = $445.20
Range = $445.20 - $201.40 = $243.80
Therefore, the mean is $339.60, the median is $318.00, the mode is $445.20, and the range is $243.80.
