Answer:
Machine B is the faster machine because it packs 4 cartons in an hour while the other machine takes 5 hours to pack 4 cartons. The faster machine can pack 4 cartons in an hour.
Step-by-step explanation:
I think it would be easier to covert the fractions to decimals here
-1.2 * 1 1/5 / 3/10
= -1.2 * 1.2 / 0.3
= -1.44 / 0.3
= - 4.8 answer
200% bc it went up 2x as much as it cost before
The width would be 236 and the lengths would be 118
Use the equations 2L+W=472 and W*L=MAX
Change the first equation to W=472-2L and plug this into the other equation
(472-2L)(L)=MAX
472L-2L^2=M (take derivative)
472-4L=0 (set to 0 to find the max value)
4L=472
L=118
Plug into original to get W=236
Hope this helps!
