x=4785/165=29
It will be in year 1996+29=2025 that estimated fees and tuition average $7556
The aluminum section's area formula solved for h is 
From the complete question, the expression of the area (A) in terms of variables a, b and h is:

Factor out h from the expression on the right-hand side

Divide both sides of the equation by (a - b)

Remove the bracket

Rewrite the above equation as follows:

Hence, the aluminum section's area formula solved for h is
