Grandma Jenkins knows that she has between six and nine months left to live. She wants to leave each of her grandchildren $1,000 when she dies. For this purpose, she has established a trust fund and has deposited sufficient monies to provide for her twelve grandchildren. Today, she just discovered that her daughter is going to going to have twins, increasing the number of her grandchildren to thirteen. To ensure her final wish is fully funded, Grandma Jenkins needs to:

• Withdraw $1000 from her trust account
• Withdraw less than $1000 from her trust account
• See if the rate of interest on her account can be lowered
• Deposit at least $1050 into her trust account
• Deposit a little less than $1000 into her trust account

Please explain to understand this question and how to solve it.
