Suppose that on January 1 you have a balance of $5000 on a credit card whose APR is 18%, which you want to pay off in 1 year Assume that you make no additional charges to the card after January 1
a Calculate your monthly payments what is the total paid since january 1st
b. When the card is paid off, how much will you have paid since January 1?
c. What percentage of your total payment from part(b) is interest?
FREE
a. The monthly payment is $ 458.40
(Do not round until the final answer. Then round to the nearest cent as needed)
b. The total paid since January 1 is $
(Use the answer from part (a) to find this answer. Round to the nearest cent as needed)

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

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 ☺

the train arrives at 20: 27 hope i
