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.
