Sorry it took a long time.
Answer:
Thor is the best deal.
Step-by-step explanation:
Thor is $10.35, Lemon is $11.73, Patrick is $14.66, and Sarah is $16.63.
For Thor, multiply $1.15(2)=$2.30. Then multiply $1.15(7)=$8.05. Add these together to get $10.35.
For Lemon, multiply 17($1.15)=$19.55. Then subtract by $7.82 to get $11.73.
For Patrick, use the equation we already did 17($1.15) and subtract $4.89 from it to get $14.66.
Last, For Sarah multiply our $19.55 (.15) to find 15% and get 2.934. Then subtract $19.56 - 2.934 to get $16.626. Round to $16.63.
Hope this helped!
