The equation y= 1725 - 75x represents the amount of money y (in dollars) left in your lunch account after x weeks. twenty weeks go by. find the domain and range of the function.

For the answer the question above asking to find the domain and range of the function. I'll show my solutions below
y= -75x +1725
y= -75(20) +1725
y = -1500 + 1725
y= 225 = range
225= -75x +1725
225 - 1725= -75x
-1500=-75x
-1500/-75 = -75x/-75
x = 20 is the domain
I hope this helped you.
