Question 44666: Barok and Zanna opened their B & Z Recycling Station one month ago, and already they have 7,000 tons of galactic debris for sale. They have collected five times as many 4-ton bins of asteroid fragments as 2-ton bins of meteorite dust. They have in storage four times as many 10-ton bins of scrap metal as 6-ton bins of electronic parts. How many bins do they have of each kind of galactic debris?

Solved using brute force and a spreadsheet.
130 of 2 ton bins meteorite dust( 260 ton)
650 of 4 ton bins Asteroid fragments (2600 ton)
90 of 6 ton bins electronic parts ( 540 ton)
360 of 10 ton bins scrap metal (3600 ton)
1230 bins in total with an included mass of 7000 ton.
