Question: George wants to borrow $100 from a loan shark. The finance fee starts at 5% and doubles every week. If George plans to borrow for 2 weeks, how much in fees will he have to pay? Think carefully first, then make a decision:
After the first week, the fee will be $100 * 5% = $5. For the second week, the finance percentage will be 5% * 2 = 10%. George will have to pay a fee of $100 * 10% = $10 for the second week. In total, George will be charged $5 + $10 = $15 in fees. So the answer is 15.
