Let x=total amount sold on Wednesday.
5% of x is what Jayne's commission was.
5% is written as 5/100=1/20.
Therefore, Jayne's commission was (1/20)x which was equal to $96.
(1/20)x=96 equation to solve
x=(96)(20) multiply both sides by 20 to isolate x
Therefore, $1920 worth of computer parts were sold on Wednesday.
