Jame gets a raise to $20 per hour and works 40 hours a week.  His old job was $16 an hour for 25 hours per week.  How much more money does he make per year in his new job than the old job if he works 52 weeks a year?
He makes 20*40=$<<20*40=800>>800 per week
He used to make 16*25=$<<16*25=400>>400 per week
So his raise was 800-400=$<<800-400=400>>400 per week
So he makes 400*52=$<<400*52=20800>>20,800 per year more
