Britania has a gross bimonthly income of $2,900. She pays 18% in federal and state taxes, puts aside 12% of her income to pay off her school loan, and puts 10% of her income aside for savings. She is considering an apartment that will rent for $1,850 per month. What is her recommended 25-30% housing expense range?

$725 to $870

Step-by-step explanation:

Federal Taxes: (2900×18)÷100=$522

School Loan: (2900×12)÷100=$348

Savings: (2900×10)÷100=$290

Housing Expense Range:

(2900×25)÷100=$725

(2900×30)÷100=$870

2900-(870+725+290+348+522)=

2900-2755=

$145 (Including savings)

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.

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 ☺
