Answer:  D. a_n=6+(n-1)(-3)

Step-by-step explanation:

Given : An arithmetic sequence has this recursive formula:

a_1=6 \ \ \; \ a_n=a_{n-1}-3

Using the given information, Second term of arithmetic sequence will be :-

a_2=a_{1}-3=6-3=3

That means common difference = a_2-a_1=3-6=-3

The explicit formula for arithmetic sequence is given by :-

a_n=a+(n-1)d, where a is the first term and d is the common difference.

Put a= 6 and d= -3, we get

The explicit formula for this sequence :-

a_n=6+(n-1)(-3)

Sue Brown is a salesperson at a car dealership. She earned a gross pay of $8000 for the month of June. Her state tax rate is 3.5
Neporo4naja [7]

Sue Brown owes $280.00 in state taxes for the month.

Step-by-step explanation:

Given,

Gross pay of Sue in June = $8000

Tax rate = 3.5%

As full amount is taxable; therefore

Amount of tax to be paid = 3.5% of pay of June

Amount of tax to be paid = \frac{3.5}{100}*8000

Amount of tax to be paid = 0.035*8000

Amount of tax to be paid = $280.00

Sue Brown owes $280.00 in state taxes for the month.
