4.4x + 1.9(200-x) = 520

4.4x +  380 - 1.9x = 520

x = 56


56 ounces of the $4.40 per ounce alloy

200 - 56 = 144 ounces of the $1.90 per ounce alloy

I don’t have a very detailed explanation, however the answer should be “A 90-degree counterclockwise rotation about the origin followed by a translation 1 unit to the left”.

You can clearly see a 90° angle here, it’s obvious. Also, the polygon switch counterclockwise. so, you can see.

hope I helped ^^
