<human>:  Bob orders a dozen muffins a day for $0.75 each and sells them for $1.5 each. How much profit does he make a week?
<bot>: How much does Bob spend on muffins? ** He buys them for 12*.75=$<<12*.75=9>>9
How much does Bob sell them for? ** He sells them for 12*1.5=$<<12*1.5=18>>18
How much does Bob make a day? ** So he makes 18-9=$<<18-9=9>>9 per day
How much does Bob make a week? ** That means he makes 9*7=$<<9*7=63>>63 per week
