Ответ:
12 skirts that take 3 yards each means 3 yards * 12 skirts which is 3 * 12. This is being subtracted from 50.
We also want to subtract 9 hats * 1 yard which is 9 * 1 = 9
Our expression will look like this: 50 - 12 * 3 - 9 * 1
or 50 - 12 * 3 - 9, which is D
Ответ:
9 hats take 1 yard each = 9*1
Remainder of yards left:
50 - 12*3 - 9*1
50 - 12*3 - 9 Option D
I hope this helps.
Ответ:
it cost 80 dollars
Step-by-step explanation:
cost per bag for X brand =25 $
cost per bag for y brand = 20$
minimize Z=(25X +20 y)
further formulate the problem
the given constraints are
2x + y equal 12
2x + 9y equal 36
2x + 3y equal 24
well on the graph given plot of the constraints
the corner points are
(0;0)
(6;0)
(0;4)
(9;2.5)
minimum z occurs at (0:4)
value of Z(minimum cost)=80$
