First calculate how much the loan shark charges in interest the first month by multiplying the loan amount by the interest rate: $200 * 10% = $<<200*10*.01=20>>20
Now add the interest amount to the original amount of the loan to find Jerry's new total: $200 + $20 = $<<200+20=220>>220
Now multiply the new total by 10% to find out how much Jerry owes the loan shark in interest the second month: $220 * 10% = $<<220*10*.01=22>>22
