Step-by-step explanation:
X + y = 120(being alternate angle)
or,X=120-y
then
2x-y=120
or,2(120-y) - y= 120
240-2y-y=120
y=240-120
y= 120
again,
X=120-y
= 120-120
=0
hence,
X= 0
y= 120
So it’s $15 per month so that is what you are gonna multiply by x. You start out with $75 so that’s the initial fee. 15x + 75 is your expression.
There is a 25% decrease because the decrease is 30, which is 25% of 120.
