Katy invests $18,000 at 14% simple interest for 1 year. How much is in the account at the end of the 1 year period? $

$20,520 at the end of the year

Step-by-step explanation:

A = P(1 + rt)

   A = Total Accrued Amount (principal + interest)

   P = Principal Amount

   I = Interest Amount

   r = Rate of Interest per year in decimal; r = R/100

   R = Rate of Interest per year as a percent; R = r * 100

   t = Time Period involved in months or years

P = $18,000

r = .14

t = 1

A = 18,000 (1+ ( .14 * 1 ) )

A = 18,000 (1 +.14)

A = 18,000 (1.14)

A = 20,520

$20,520 at the end of the year

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

answer: 2530

hope this
