Homework Statement
Hello all,
Can someone help me figure this out?
"It takes cosmic stitching 2 hrs of cutting and 4 hrs of sewing to make a knit suit.
To make a worsted suit, it takes 4 hrs of cutting and 2 hrs of sewing. At most 20 hrs per day are available
for cutting and at most 16 hrs are available for sewing. The profit on a knit suit is $68 and the profit on a worsted suit is $62. How many of each kind should be made to maximize profit?"
Homework Equations
These are the eqn's/ inequalities I came up with:
Let c = cutting
Let s = sewing
c (less than or equal to) 20
s (less than or equal to)16
c+s (less than or equal to) 24 hrs
The Attempt at a Solution
I graphed c on the y-axis and s on the x-axis and found the two points of intersection of the function c=-s+24
they are (4,20) and (16,8).
Not sure what to do know (note I got to the answer by using logic, but the books answer has the answer in (x,y) form, which means that they somehow created a graph of knitted suits vs. worsted suits...
Can anyone help?
P.S You can be straight to the point, as embarrassing as it is, I tutor up through most of calc and physics.
Its been years since I have done these types of problems, and this one was presented to me at the tutoring center at which I work.
