Nancy works for a company that offers two types of savings plans. Plan A is represented by the function 𝑔(𝑥) = 250 + 3𝑥, where 𝑥 is the number of quarter years she has utilized the plan. Plan B is represented by the function (𝑥) = 250(1.01)^x , where 𝑥 is the number of quarter years she has utilized the plan. Nancy wants to have the highest savings possible after five years, when she plans to leave the company. Which plan should she use?

• Plan A

• Plan B
