Question 1047044
x = weekly allowance.
she spends half to play mini-golf.
her parents let her wash the car for 4 dollars.
she ended up with 12 dollars.


x - 1/2 * x + 4 = 12


simplify to get 1/2 * x + 4 = 12.


subtract 4 from both sides of the equation to get 1/2 * x = 8.


solve for x to get x = 16.


her weekly allowance was 16.


she spent half on mini-golf and was left with 8.


her parents gave her 4 to wash the car.


she was left with 12 after all that.
