(20 points) Lynn Carter is paid $3000 every 30 days. Her salary is deposited initially in her bank. She spends all her money at a constant rate over the 30 days and must pay cash. She can 1) withdraw all of the money at once; 2) withdraw half at once and the rest after 15 days; 3) withdraw one-third at once, one-third after 10 days, and one-third at 20 days; 4) make any number of evenly spaced withdrawals. Each withdrawal costs her $2 in terms of time and inconvenience. For each day that Lynn has a dollar in the bank, she gets 0.06 cents (0.0006 dollars) in interest. 1) (15 points) Create a table showing transaction costs, interest earned, and surplus associated with one, two, three, four, and five withdrawals per month. 2) (5 points) How many withdrawals per month lead to the largest surplus? If Lynn chooses this number, what is her average amount of cash on hand over the 30 days
