3132/ month x 9 months = 21,188 chairs
A)
I:2.25*pretzels+1.5*drinks=463.50
II:pretzels+drinks=257
b)
with II:
pretzels+drinks=257
pretzels=257-drinks
substitute pretzels=257-drinks into I:
2.25*pretzels+1.5*drinks=463.50
2.25*(257-drinks)+1.5*drinks=463.50
2.25*257-2.25*drinks+1.5*drinks=463.50
-0.75*drinks=463.5-2.25*257
0.75*drinks=114.75
drinks=114.75/0.75=153
in II:
pretzels=257-drinks
pretzels=257-153=104
