Six hundred two thousand one hundred seven.
X=5/9
Y=0.65
See below the following picture for the solution
To determine the amount of gold plating necessary for the similar box, you will use the fact that it is 8 times larger in volume to determine how many times larger the area is. This would be what you will multiply $125 by.
Volume is a three dimensional measurement, so the fact that it is 8 times larger tells us each dimension was 2 times larger (2 x 2 x 2=8).
Area is a two dimensional measurement, so the area would have been 2 x 2 or 4 times larger. This means the price would be 4 times as much.
$125 x 4 = $500.
It will cost $500 to gold plate the similar jewelry box.
Well to eliminate x you will need to make the positive value of x in one equal the negative value in the other.
hence you can either multiply A by 5/2 or B by 2/5 which brings you to either 2 or 3, but as x is negative in B already, you add. resulting in the answer being the 3rd one down (i think)
