Ari wants to save up to buy a new computer, which costs $1,100. She received $500 for her graduation and decides to invest the money in a fund where she can earn interest on her money. Use the simple interest formula for plan A and the compound interest formula for plan B. Plan A Plan B 6.5% interest on the original balance each month for 12 months. 6.5% interest on the balance in the account each month. Ari has previously determined that she should use plan B because she will have $890.00 after 12 months using plan A and $1,064.55 after 12 months using plan B. After 12 months, she still does not have enough money to buy the computer. How many more months will it take her to reach $1,100 using plan B? Using Plan B, Ari would need nothing more month(s) to buy her computer.

step-by-step explanation:

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.

if i did my math right then the answer should but 108
