<p>i don’t know how to solve this problem and i don’t the explanation</p>

<p>Each of the variables t, w, x, y, and z represents a different positive real number. Given the equations below, which of the 4 variables w, x, y, and z necessarily has the greatest value?</p>

<p>1.23w = t
1.01x = t
0.99y = t
0.23z = t</p>

<p>F.w
G.x
H.y
J.z
K.Cannot be determined from the given information</p>

<p>ANS :J
EXPLANATION:J is the correct answer. If you solve each of the equations in terms of t, you get w = 0.81t; x = 0.99t; y = 1.01t; and z = 4.35t. Since the value of t is fixed, 4.35t will give the largest number, so z will have the largest value.</p>

<p>Thnk about if t was 1000 apples and 1,2,3,4 were numbers of boxes. Let w,x,y,z be the number of apples per box.</p>

<p>The more boxes you have (4 boxes), the less apples you will have in each box (250). The less boxes you ahve (1 box), the more apples you have in each box (1000). Thus, the lowest number of boxes (1,2,3 or 4) will give you the biggest #apples per box (w,x,y,z).</p>

<p>In this case, the lowest number of boxes is .23. This will give you the biggest" number of apples".</p>
