Hannah’s current earnings are 20% greater than the category average, which makes them 1.2 × $750 = $900 per week. If she takes a 50% pay cut for 30 weeks, her lost wages will be 900/2*30=$13,500. Adding that to the college expenses of $6,000, Hannah needs to make up a total of $19,500. When she gets her degree, Hannah will be making $1,200 per week. If she hadn’t cut back her hours to attend school, she would still be making $900 per week, so she is recouping her $19,500 at the rate of $1,200 − $900 = $300 per week. So, it would take Hannah $ 19,500/300=65 weeks

I don't get this why are we doing this subtraction, can't we just put 19500/1200=16 weeks
