Answer 1

An explicit rule for the student's savings account with a starting deposit of $400 and additional monthly deposits of $25 is M = 400 + 25n. After 12 months, the account will have $700.

Step-by-step explanation:

To write an explicit rule representing the amount of money deposited into a savings account, we consider the initial deposit and the regular monthly deposits. In this case, the initial deposit is $400, and there is an additional deposit of $25 each month. The explicit rule can be defined as M = 400 + 25n, where M represents the total amount of money in the account after n months.

To calculate the total money in the account on month 12:

Plug 12 into the explicit rule for n: M = 400 + 25(12).

Calculate the total: M = 400 + 300 = 700.

Therefore, at month 12, you will have $700 in the savings account.

Answer 2

Rule: 400 + 25x

After Month 12: 700 dollars

Step-by-step explanation:

To start, we need to set a variable as the amount of months after you started your savings account. Call this value x. Now, we just have 25x as the amount you gain after x months, so the rule is 400 + 25x. To calculate how much you have after month 12, just plug in 12 to get 400 + 300 = 700 dollars.
