Mike, Tom, and Walt are working as sales agents for an insurance company, and the commissions they receive can be expressed by the following formula: MT=W/6 . If Mike sells 60% more this month and Tom decreases his sales by 50%, how should Walt's performance change to ensure that the above relationship is true ?

I believe this is the same question that has already been answered. But here's my take:

MT = W/6 => 6MT = W (1)

1.6M * 0.5T = Wx/6 0.8MT = Wx/6 4.8MT = Wx (2)

Comparing (1) and (2):

(1) 6MT = W (2) 4.8MT = Wx

Since 4.8 is 4/5 of 6, x would need to be 4/5 for the equation to hold. Therefore, W needs to decrease by 20%, or answer choice B, for the equation to remain intact.
