Sun Valley High School is trying to raise money for their band program. Nike and Adidas are both willing to sponsor their 5k walk/run using different financial plans. Nike promises to double the amount of money they contribute every kilometer, and will start with a $4 donation. Adidas promises to start with a $30 donation and will add $10 for every kilometer.

Which statement best describes which plan Sun Valley High School should choose and why?

A) Adidas starts off being the better plan because they contribute more at the start, but Nike ends up giving twice as much money as Adidas.

B) Nike is the better plan because they end up giving more total money since they are doubling.

C) Adidas ends up with a total of $80, but Nike only contributes $64, so Adidas is the better plan.

D) Adidas is the better plan because adding patterns are always better than doubling patterns.
