Five machines can produce 12 gallons of Glorious Goo in 10 days.
How many days would it take 4 machines to produce 48 gallons?
:
Using machine-days as a work unit
5*10 = 50 machine days to produce 12 gal
that's
50%2F12 = 41%2F6 machine-days/gal
:
"How many days would it take 4 machines to produce 48 gallons?"
48 * 41%2F6 = 200 machine-days to produce 48 gal
then
4d = 200
d = 200%2F4
d = 50 days

4 machines take 50 days to produce 48 gal
