When x is 2, y is 4, p is 0.5, and m is 2. If x varies directly with the product of p and m and inversely with y, which equation models the situation?

xpmy=8

xy/pm=8

xpm/y=0.5

x/pmy=0.5

The correct answer for the question that is being presented above is this one: "xy / pm = 8." The equation that models the situation is this xy / pm = 8

If x varies directly with the product of p and m and inversely with y:

x = pm/y

2 = 0.5*2 / 4

8 = 1

Then,

xy / pm = 8
