A math problem for fun, cant solve it!

Post by n2x4 »

How sad is it that I'm starting to find math problems fun to solve :roll:

http://puzzle.arpatubes.net/

That site posts a new word problem every week. This week has me stumped. This is what I have so far-

V=450,000,000mL
One 1:5 mix = 2000mL
Cost of one mix = $31.25

I'm factoring in 9/10ths to give me 405,000,000mL
divide by 2000 then multiply by 31.25

Am I missing something?

Got it! Enlisted the help of 3 coworkers and we came up with my issue. My ratio was wrong!

Isn't Canada supposed to use metric?
