How could The Lovely Bones be framed as a coming of age story?

Thanks

[Known Information] Based on the information in the problem statement, we know that
Carlos purchases a total of ten pounds of meat. We know that hamburger costs four
dollars per pound and steak costs nine dollars per pound. We also know that the total
cost of the meat Carlos purchases is seventy dollars. [Unknown Information] Of the ten
pounds of meat that Carlos purchased, we don’t know how much was hamburger and
how much was steak. [new screen, first button] The problem tells us that hamburger
costs four dollars per pound. [second button] The problem tells us that steak costs nine
dollars per pound. [third button] The problem tells us that the total amount of meat that
Carlos purchased is ten pounds. [fourth button] We don’t know how much hamburger
Carlos purchased, so this is an unknown. We will let x represent the number of pounds
of hamburger Carlos purchased. [fifth button] Since Carlos purchased a total of ten
pounds of meat and x of those ten pounds were hamburger meat, then ten minus x
pounds were steak. [sixth button] The total cost of the hamburger meat is the cost per
pound times the number of pounds, or simply four x. [seventh button] The total cost of
the steak is the cost per pound, or nine dollars, times the number of pounds, ten minus
x. [eighth button] The total cost of the meat that Carlos purchased is seventy dollars.
[new screen] The amount of money Carlos paid for hamburger plus the amount of
money he paid for steak equals the total amount of money he paid for the meat. You
can use the table to help you set up the equation. The information we need appears in
the last column. The amount Carlos paid for hamburger meat is four x. The amount
Carlos paid for steak is nine times the difference ten minus x. The total amount of
money Carlos paid for the meat is seventy dollars. The equation for this problem is four
x plus nine times the quantity ten minus x equals seventy. [new screen] Now, we can
solve the equation. First, simplify the left side. Use the distributive property to expand
the product of nine and the difference ten minus x. Combine like terms. Subtract ninety
from both sides. Then divide both sides by negative five. x equals four. Since x
represents the number of pounds of hamburger meat that Carlos bought, we can say
that Carlos bought four pounds of hamburger meat. He also bought ten minus four, or
six, pounds of steak. [new screen] Finally, check the solution. Replace x with four in the
