If sales tax is 8.6 % find the total cost, including tax of a car stereo with a selling price of $395

428.97

Step-by-step explanation:

The first step is to find the sales tax

tax = original price * tax rate

tax = 395 * 8.6%

     = 395*.086

     =33.97

Now we need to add this to the original price

new price = original price + tax

                 =395+ 33.97

                =428.97

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
