Her weekly allowance is $236.

Explanation:

Let "W" represent her weekly allowance.
Then, since she spent half of it playing mini-golf, she has half of it left.
Let #W/2# be the amount she has left.
Then with the $4 she earned from washing the car, she now has $122. Represent this fact with an equation and solve for "W":

#W/2 + 4 = 122#
#W/2 = 122-4#
#W/2= 118#
#W = (118)(2)#
#W= 236#
Her weekly allowance is $236.
