A wholesaler wishes to sell 100 pounds of mixed nuts at $2.50 a pound. She mixes peanuts worth $1.50 a pound with cashews worth $5.00 a pound. How many pounds of cashews must she use?
[ "A)40", "B)45", "C)50", "D)55" ]
B
From the question stem we know that we need a mixture of 100 pounds of peanuts and cashews. If we represent peanuts as x and cashews as y, we get x + y = 100. Since the wholesaler wants to sell the mixture of 100 pounds @ $2.50, we can write this as: $2.5 * (x + y) = $1.5x + $4y From the equation x + y = 100, we can re...

Arterial hypoxemia is defined as an arterial P02 (partial pressure of oxygen) less than 80 mmHg, who is breathing room air at sea level. And because the partial pressure of a gas is determined by the soluble fraction of gas and not by the amount carried chemically bound to hemoglobin - the Hb does not determine P02 and...

An alloy weighing 18 ounces is 70 percent gold. How many ounces of pure gold must be added to create an alloy that is 90 percent gold?
[ "A)6", "B)90", "C)12", "D)24" ]
B
In 24 ounces, gold is 18 * (70/100) = 12.6 ounces. Now we add x ounces of pure gold to make it 90% gold. So 12.6 + x = (24 + x)* 90/100 => x =90. Answer is B.
