In the United States, of the people who moved from one state to another when they retired, the percentage who retired to Florida has decreased by three percentage points over the past ten years. Since many local businesses in Florida cater to retirees, this decline is likely to have a noticeably negative economic effect on these businesses. Which of the following, if true, most seriously weakens the argument?
(A) Florida attracts more people who move from one state to another when they retire than does any other state.

(B) The number of people who move out of Florida to accept employment in other states has increased over the past ten years.

(C) There are far more local businesses in Florida that cater to tourists than there are local businesses that cater to retirees.

(D) The total number of people who retired and moved to another state for their retirement has increased significantly over the past ten years.

(E) The number of people who left Florida when they retired to live in another state was greater last year than it was ten years ago.

Hello,

The author says "There will be a noticeable negative economic effect on these businesses"

This he says because the percentage who retired to Florida has decreased by three percentage points over the past ten years

Let's understand what this means - Out of all the retirees who retired to different locations the percentage of people who retired to florida has dropped by 3%.

For instance if the percent of retirees retiring to florida was 33% it's probably dropped to 30% now. The assumption here is that the total number of retirees now and 10 years back is more or less the same.

Lets consider that 10 years back there were 10,000 total retirees; now there are probably 20,000. Is 33% or 10,000 bigger than 30% of 20,000? nope!

Option D points out exactly this. Thus option D is Correct.

Hope this helps!

step-by-step explanation:

step-by-step explanation: so we look at the formula un = a + (n-1)d

un is the amount of seats

n is the nth term aka row number

a is the original sequence/row number

d is the difference between each term

so in this a=22 d=6 and n can remain as n because we are simply formjng a rule

lets put these in the equation

un=22+(n-1)(6)

this is your answer to part a

however

lets double check that this is correct, we'll try putting it into the second term

un=a+(n-1)d

u2=22+(2-1)(6)

u2=22+6

u2=28

as the question said the second row has 28 seats so now we know the formula we made is correct.

as for part b

un=a+(n-1)

its asking us to find a row with 100 seats.

remember un was the amount of seata so all we do is substitute this in.

un=100 a=22 d=6

un=a+(n-1)d

100=22+(n-1)(6)

so now we simplify to find n which is the row number.

100-22=22+(n-1)(6)-22

78=(n-1)(6)

78/6=(n-1)(6)/6

13=n-1

13+1=n-1+1

14=n

so now we know that in the 14th row there is 100 seats.

hope this and that you understood! its my first time using the app or anyone out on here : p its also me to revise so a bunch! ask more questions if you dont understand ☺
