The charity will receive $ 11
<h3><u>
Solution:</u></h3>
Ken earned $176 from his part-time job this summer
Amount earned = $ 176
He spent 25% of his money on games
Therefore,
Money spent on games = 176 - 25 % of 176

He is going to donate 1/4 of the remaining money to charity
Reamining amount = 176 - 132 = 44
Therefore,

Thus he gave $ 11 to charity
