Question

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?
A.plan A
B.plan B
C.plan C
D.plan D

Answer 1

Plan B is the correct answer on edguniuty

Answer 2

Plan A and D are wrong because plan C says it would be the same price for 8 weeks but the amount of time it would take to reach $12 for plan D would be 16 weeks so this cancels plan A and D. If you were to add %10 each week then it would take 5 weeks to reach $12 because %10 of $8 is 80 cents so 80 cents times 5 is $4 and 4+8=12 Thus proving B is correct
