Answer:
His weekly allowance is 20 dollars
Step-by-step explanation:
the full equation would be (with x equaling weekly allowance):
(x÷2)+6=16
subtract 6 from each side to get
(x÷2)=10
then multiply each side by 2
x=20
Weekly allowance is $10. He ended with $16, so subtract 6 from 16 to get 10. $10 was the amount he still has left, and since he spent half multiply 10 by 2 to get $20
