is the answer B?

since we know that one of the side is 1, so the largest length of the other side is 1. so A = 0.5bh = .5*1*1 = .5

hi.

are you sure the answer is C?

I would think it is E, because even though you have the ratios for each, answer B just states that the number of Women is less than 30 (i.e. 5, 10, 15, 20 , 25). Because this is not a constant value, we cannot determine the values of the others.

hi.

.01x + .02y + .03z = 0.15(x+y+z)
x + 2y + 3z = 1.5(x + y+ z)
.5y + .15z = .5x
5y + 15z = 5x

x = y + 3z
