Two companies are competing for a contract to sell the school wifi. Comporium charges a $100 fee for installation and $39.99 for each month of service.
Brighthouse charges a $20 fee for installation and $49.99 for each month of
service. For what number of months of service will Comporium cost more than
Brighthouse?

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

found it xd it ok yt

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
