Sasha has a coupon to a local store that gives her 15% off one item. If the item she buys costs ddollars, the amount she will be charged can be represented by this expression
0.850
Which of these is equivalent to the expression?

1 d+0.15d
2 d-0.15d
3 0.15d
4 1.15d

2

Step-by-step explanation:

If d was $10 then 10x.15= $1.50. Then you take 10-1.5 and get $8.50

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.

d. is the correct answer
