Of the 50 electronics components that a factory must
manufacture, 70 percent would be most e¢ ciently manufactured
by Machine A and the remaining 30 percent would be most
e¢ ciently manufactured by Machine B, though either machine
could manufacture any of the 50 components. If 36 percent of
the components were manufactured by Machine A and the
remainder were manufactured by Machine B, what is the
highest possible number of components that were
manufactured by the machine that would manufacture them
the most efficiently?
Pick one.
A) 30	B) 31	C) 32	D) 33	E) 34
# components A and B could manufacture efficiently:   A: 50*70% = 35   B: 50*30% = 15   # components A and B effectively manufacture:   A: 50*36% = 18   B: 50*64% = 32   Max. # components efficiently manufactured:   18 (from A) and 15 (from B) = 33   ANSWER:33
