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? Think carefully first, then make a decision:

He buys them for 12 * .75 = $9. He sells them for 12 * 1.5 = $18. So he makes 18 - 9 = $9 per day. That means he makes 9 * 7 = $63 per week. So, the answer is 63.
