A store sells 5 models of cameras for $260, $120, $220, $300, and $120. If the sales tax rate is 2%, what are the mean, median, mode, and range of the total cost of the cameras?

a. Mean = $244.40
Median = $208.08
Mode = $122.40
Range = $16.32

b. Mean = $208.08
Median = $224.40
Mode = $122.40
Range = $183.60

c. Mean = $122.40
Median = $224.40
Mode = $208.08
Range = $183.60

d. Mean = $208.08
Median = $224.10
Mode = $122.40
Range = $16.32

Respuesta :

B.

Mean: 208.08

Median: 224.4

Mode: 122.4

Range: 183.6

First, we can make it easier by rearranging them from least to greatest in proper numerical form.

$120, $120, $220, $260, $300

Mean: (120 + 120 + 220+ 260 + 300)(1/5)=1020

1020 x 1.02( tax rate) = 1040.4

1040.4/5= 208.08

Median: %220 x 1.02= 224.4

Mode: 120 x 1.02 = 122.4

Range: (300 x 1.02)-(120 x 1.02)= 306-122.4

306 - 122.4 = 183.6
