I just took a quick look here and noticed immediately that you say the small girl weighs more than the big girl.
259 pounds (72 inches/63 inches) = ?

In 19 you made the same mistake, smaller should be less but they may be trying to trick you. What do they mean by size? If the length and width are half and the height the same, the area is 1/4 of 9100 and the cost is (1/4)($306). The question is not clear.
Oh come on. 0.17 * 180,000 is NOT 72,941.
That makes no sense at all. How on earth did you get it?
I am out of here, have grand kids to help.
