To give money and spread awareness of homelessness alaska made an organization and gets money for the homeless from fees from new members. there were 587 new members that were 18-24 years old and they have to pay $10 in fees. the rest who were older than 24 years old had to pay $15 in fees. if there are 1942 new members in total, how much money did alaska contribute to stop homelessness?

$26,195.

Step-by-step explanation:

total of new members(1942) - age group 18-24 (587)= new members(1355) to pay $15 each in fees.

1942-587=1355 x$15=20,325

next: take age group 18-24 (587)and multiple by $10 fee

587 x$10=5,870

last add both numbers together:

$20,325+ $5870=$26,195

$6.42

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 ☺
