I thought they would be the same so I would go with B. 85
<span>Since the number of nail boxes is 6 less than the number of yards of wood, the right expression to use is x-6. (x being the number of yards of wood)
Now let us calculate the number of nail boxes she bought.
Cost of x yards of wood at $27 per yard = 27x.
Cost of x-6 boxes of nails at $4 per box = 4(x-6) = 4x - 24
Therefore 27x +4x - 24 = 193
31x -24 = 193
31x = 193 + 24
31x = 217
x = 217/31
= 7
So she bought 7 yards of wood and 7-6 boxes of nail. That is, she bought only one box of nail.</span>
We can see in the "x" function, the numbers are moving (+1).
The first thing that we would do is to subtract both (-5.3 - -2.45) and our answer would be -2.85.
So, for every (+1) on the x function, the y function would (-2.85).
y= (-2.85)
x (+1)
The surface area is 33 meters
