Coral spent half of her weekly allowance playing mini-golf. to earn more money her parents let her wash the car for $4. what is her weekly allowance if she ended with $12?

X=weekly allowance
x/2=money saved  (=  money spent).
We can suggest this equation:

x/2+4=12

lowest common multiple=2
x+8=24
x=24-8
x=16

her weekly allowance is $16.
