The Polleys want to put in a swimming pool next summer. They need to save $7,000 over 12 months in order to achieve this goal. They set aside the same amount each month and after 6 months discovered they have saved $3,200. The Polleys know that they must adjust their plan in order to meet their goal, so they come up with the following options Option A: Save the original amount each month but put the pool in one month later than originally planned. Option B: Increase savings each month by $125 from their original plan. Which plan, if any, will work for the Polleys?
