Let's say that Scott gets x cents for his allowance. We know he spent cents on the newspaper, cents on the snack, and he has 220 cents remaining. Assuming no additional purchases or expenditures, these three amounts must add up to his total allowance, or:

cents, or $4.50.

Check your answer:

One-ninth of $4.50 is $0.50. Two-fifths of $4.50 is $1.80.

$0.50 + $1.80 = $2.30 and $4.50 - $2.30 = $2.20.
