1.Suppose you receive $100 for a graduation present and you deposit it in a savings account. Then each week thereafter, you add $5 to the account, but no interest is earned. The amount in the account is a function of the number of weeks that have passed. Let x represent the number of weeks.
Let y represent the amount of money in the account.
Part A. Write an expression that relates the graduation present to the money you deposit into the account.
Part B. Write an equation for the amount of money a that you have after x weeks.
Part C. Use your equation to find when you will have $310 in your account.
