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.
