There is no restriction upon the domain, the x values, and is all real numbers or (-oo,+oo)

D.
or divide 900 by 20 and see the closest
The answer would be $50 per blender.
To explain the way I did it --
Toaster ovens - 70 * 5 = 350
70 - 20 = 50
Blenders - 50 * 3 = 150
350 + 150 = 500
2 2/3 + 1 3/5
= 2 10/15 + 1 9/15
= 3 19/15
= 4 4/15
answer is 4 4/15 (4 and 4/15)
