He receives $53 after three hours of babysitting.

Explanation:

Setting up a proportion ($5.50)/(30min) = (x)/((3)(60)min) => 5.50/30 = x/180 => 30x=(5.50)(180) => 30x = 990 => x =33
Remember that Jeanne charges a $20 fee for the day, adding that to our total, we have:
$33 + $20 = $53 => He receives $53 after three hours of babysitting.
