Dan spent half of his allowance going to the movies. He washed his family car and earned $6. What is his weekly allowance if he ended with $16? write an equation and solve.
subtract the 6 from 16 to get what he had before he earned the $6 to get 10, but if he spent half of his allowance you would add another 10 to the other ten to get $20 so his weekly allowance is $20
