Rebecca is using two different baking pans to bake bread for a bake sale. If the dimensions of the first pan are 4 x 8 x 3 inches, and the dimensions of the second pan are 9 x 9 x 2 inches, what is the total volume of both baking pans, in cubic inches?

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.

add -60 to 120 which will result in : 2x+3y=180

then subtract 2x: 3y=-2x+180

lastly, divide by 2: y= -2/3x+60

hope this is the answer you're looking for: )
