Felix’s Feed Mill sells chicken feed for $8.00 per bag. This price is no longer high enough to create a profit. Felix decides to raise the price. He is considering four different plans.Plan A: Raise the price by $0.10 each week until the price reaches $12.00.Plan B: Raise the price by 10 percent each week until the price reaches $12.00.Plan C: Raise the price by the same amount each week for 8 weeks, so that in the eighth week the price is $12.00.Plan D: Raise the price by $0.25 each week until the price reaches $12.00.Which plan will result in the price of the feed reaching $12.00 fastest?

Answer
A
plan A
B
plan B
C
plan C
D
plan D

Explanation

With Plan B, the price is multiplied by 1.10 each week. After 4 weeks, it is $8.00 × 1.10⁴ ≈ $11.71, and after 5 weeks it is about $12.88, so it passes $12 in 5 weeks. Plan C takes 8 weeks, while Plans A and D take 40 and 16 weeks, respectively. Therefore, Plan B, the 10 percent weekly increase, is fastest.
