10079251057-y1+1201943289-y2≥200000

To solve the inequality, we need to find the range of values for y1 and y2 that satisfy the inequality.

100792.5*(10.57 - y1) + 1201943.2*(8.9 - y2) ≥ 200,000

First, let's simplify the equation:

19850*(10.57 - y1) + 73920*(8.9 - y2) ≥ 200,000

Now, distribute the values:

209938.5 - 19850y1 + 656448 - 73920y2 ≥ 200,000

Combine like terms:

866386.5 - 19850y1 - 73920y2 ≥ 200,000

Subtract 866386.5 from both sides:

-19850y1 - 73920y2 ≥ -666386.5

Now, divide both sides by -1:

19850y1 + 73920y2 ≤ 666386.5

Therefore, the inequality can be written as:

19850y1 + 73920y2 ≤ 666386.5
