1. Sharon Wilson is single and has health insurance benefits as shown in the table. Her recent network health care costs include co-payments for 9 physician visits and 10 specialist visits. Following hospital surgery, she made co-payments for 15 physical therapy visits at $95 each and she had 5 co-payments at her local pharmacy, 2 generic and 3 brand name drugs. Her hospital admission charge was $240 and she had a hospital bill for $54,860. Find the amount she paid a. for the deductible.
b. in total co-payments.
c. in hospital charges.
d. in total costs.

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 ☺

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
