Rachel makes $12.00 as a waitress in a coffee shop.  In one hour, she serves 20 different people and they all leave her a $1.25 tip.  How much money did she make in that hour?
She served 20 people and they all tipped her $1.25 so she made 20*1.25 = $<<20*1.25=25.00>>25.00 in tips
She makes $12.00 an hour and she made $25.00 in tips so she made 12+25 = $<<12+25=37.00>>37.00 in one hour
