Help with sales tax rate?

A store sells five models of cameras for $190.00, $420.00, $270.00, $300.00, and $420.00. If the sales tax rate is 6%, what are the mean, median, mode, and range of the total cost of the cameras?

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

1 Answer

  • 190,….. .270,….. 300,….. 420,….. 420 without tax

    201.40,.286.20, 318, 445.20, 445.20 with tax

    mode 445.20, median 318

    Range 445.20 – 201.40 = 243.80…..B is the answer

    I don’t need the mean (sum of all)/5

    because only B is possible based on other 3 measures.
