About 1920, just find the volume by multiplying length times width times height
and divide that by the 1-inch cubes. hope this helps
This isn't really mathematics but I can give you an answer.
Assuming, it's in the dark (cuz in the light, why would you use flash), a person in the photograph can gain a red-eye (in the photo).
The only one I can think of is red eye.
20x-1000 +4000 = 60x
20x-60x= -4000 +1000
-40x= -3000
x= -3000/-40
75 The mix will be 75 lbs
And $20 coffee will be 75 -50 = 25lbs
3 divided by 8 = 0.375
0.375 x 100 = 37.5%
37.5% is closest to 38%
