8. Stephanie bought a pair of earrings for $3.25 and a necklace for $5.25. The tax rate is 8%. What is the total cost including tax?

$9.18

Step-by-step explanation:

you add the cost of the necklace and earring and multiply the cost by 1.08 to represent the tax

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

25% is the answer
