simplify: -3x=-6
divide both sides by -3:
simplify: x=2
Its A

Answer:
Jose will need 39.25 square inches of paper to wrap the stack of coins
Explanation:
The resulting figure of a stack of 100 coins will be a right circular cylinder. We assume that Jose wraps around the cylinder (so it means not including the bases). Therefore we are solving for the lateral surface area of the cylinder: LSA = 2πrh.
To solve for height h, we multiply the thickness of the coin 100 times.
h = 100 * 1/8 in = 12.5 inches
Solving for radius r:
r = 1 inch/2 = 0.5 inches
LSA = 2(3.14)(0.5 in)(12.5 in) = 39.25 square inches
