Icould use some with these two problems. i also need with my question before this one. option #1: annual club membership at a fee of $125 per year plus an option of prepaying for unlimited music downloads at a rate of $10 per month. 1. write a function that best models the total cost of club membership plus downloads under option #1. 2. for membership option #1, calculate the total cost for one year of club membership and prepaid unlimited music downloads.

1. a one time fee of $125 plus $10 per month for downloads

c = total cost

m = number of months

 so equation would be c = 125+10m

2. 1 year = 12 months

 so you get c = 125+10(12)=

c = 125 +120

c = $245

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
