The rate for mowing a lawn is $14 per hour. David mowed for 2 hours a day for a week. He then spent half of the money he made from mowing a lawn on a pair of shoes and gave half of the remaining money to his mom. How much money did he have left?

David got $14 / hour x 2 hours / day = $28 per day from mowing. So in a week, he had $28 / day x 7 days = $196. A pair of shoes cost $196 / 2 = $98. David gave his mom $98 / 2 = $49. The total amount he spent and gave is $98 + $49 = $147. David is left with $196 - $147 = $49.
Thus, the answer is 49.
