Shanice spent half of her weekly allowance buying pizza. To earn more money her parents let her weed the garden for $6.10. What is her weekly allowance if she ended with $10.11?

Her weekly allowance is $8.02. To figure it out you would start by subtracting the extra $6.10 from the final $10.11. You get $4.01 which would be how much she spent on pizza, so you would double it to get the original price.
