Answer:
A) y= 40x+100
B)
Step-by-step explanation:
To solve this, we can set up an equation using y=mx+b.
'b' is the initial cost, whereas 'm' is the monthly cost. This gives us the equation:
A): y=40x+100.
For part B, we can solve for the inverse by switching the x and y. This gives us:
x= 40y+100
Now, continue simplifying to isolate the 'y' on a side:
x-100=40y
