Derek owns a landscape business. he charges a fixed fee of $30 plus $1 per 1,000 square feet of lawn mowed. derek's earnings (in dollars) in the past five weeks are {204, 344, 450, 482, 504}. to find the corresponding square footage of lawn mowed, construct a function that models the total area of lawn that derek mows based on his earnings. based on derek's earnings, the corresponding square footage of the lawns he mowed in the past five weeks is

Let
x = earnings, dollars
y = area mowed, in 1000's of square feet.

Then the required function is
y = x - 30

Construct a table that shows Derek's weekly earnings versus area mowed.

week       x            y
------- --------  ----------
    1     204         174
    2    344         314
    3    450         420
    4    482         452
    5    504         474
-----   -------   -----------
Total  1984      1834

A graph of y versus x is shown below.

From the table, obtain the total area mowed in the past five weeks as the sum of the y columns, which is 1,834 thousand square feet.

1,834 thousand square feet.

X^4 + 36x^2 = x^2(x^2+36)= x*x*(x+6i)(x-6i) mark me brainliest

The answer is $9.90 with rounding to the nearest tenth
