Question 313577
Zvia's sweater cost twice as much as her hat, and a third as much as her coat. Her coat cost $114. How much did her sweater cost?

Part of the difficulty with this problem is that there is uneccesary information. The only information you need is:

Zvia's sweater cost......a third as much as her coat. Her coat cost $114.

so cost of sweater={{{(1/3)114}}}
-----------------> = $38
