Answer 1

Hello Jerome,

Let x = skirts 

Let 2x = dresses 

According to the problem these two added together equal 120. Therefore,

x + 2x = 120 

3x = 120 

x = 40 

Then: 

2x = 2*40 = 80 

Your answer is 40 skirts and 80 dresses. 

Proof our work: 

Is there twice the number of dresses than skirts? Yep.
