Jerry plans to begin saving money for a trip by putting $1 in a savings account the first month and then adding enough to double the amount in the account each following month Part A:
after he finishes contributing to the account, he will withdraw $500 to make a down payment on the trip. Create a function to show how much money will be in the account if he finishes contributing to the count after t months.

Part b:
Gary plants to keep up his saving pattern and said he can no longer afford it. At the time, he holds to have enough in his account for his trip. How much will be in the account, after making the down payment, if the most he will be able to contribute in a month is $1,200?

Part c:
Jerry's friend Brandon is planning to start saving for a trip at the same time I Jerry. The graph shows the balance in Brandon's account over the first few months of saving. Whose account will have the greatest balance after the first five months of saving, Brandon's or Jerry's?

Part d:
how long will it take for the person with the smaller account balance after 5 months to have the greater balance?

Part e:
Brandon will always need to withdraw $500 to make a down payment on the trip. How much will be in Brandon's account, after making the down payment, if he contributes for the same amount of time as Jerry? (review your calculations in Part B to determine how long Jerry continued his Savings Plan.)
