None of the above.

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this

Y= - 4x +3if you test it with any of the x values for example x=2: -4(2)+3 = - 8 + 3 = - 5you get the matching ^^^ y value
