L = 10
Total available LABOR is 10 man-hours.
b = .5
half an hour of LABOR is needed to BAKE one loaf of BREAD
c = 1
one hour of LABOR is needed to WEAVE one yard of CLOTH
Suppose we want 6 loaves of BREAD.
QB = 6
How much CLOTH can we produce?
QC = ?
BAKING 6 loaves of BREAD takes 3 hours of LABOR.
LB = b QB = (.5) 6 = 3
7 hours remain for WEAVING CLOTH
LC =< L - LB = 10 - 3 = 7
In 7 hours we can WEAVE at most 7 yards of CLOTH
QC = LC/c = 7/1 = 7
