I’m pretty sure it is 27.89 cm^2
Answer:
See below
Step-by-step explanation:
The formula for calculating percent is
% = (cost of item/total cost) × 100 %
% = (cost of item/1875) × 100 %
% = (cost of item/18.75) %
You can use the same formula to calculate the percent for each item in the budget. For example,
Housing: % = 420/18.75 = 22 %
You can do this for each budget item and get the table below.

The vertex (minimum) of the quadratic ax² +bx +c is located at x=-b/(2a). This means the minimum value of f(x) will be found at x = -3/(2*1) = -1.5.
Since the vertex of the quadratic is less than 0, the maximum value of the quadratic will be found at x=2, the end of the interval farthest from the vertex.
On the given interval, ...
the absolute minimum value of f is f(-1.5) = ln(1.75) ≈ 0.559616
the absolute maximum value of f is f(2) = ln(14) ≈ 2.639057
