Question

Marco is starting a savings account. He begins his account with $25. Each month he plans to add an additional $25.

Marcos aunt wants to know how many months it will take for his account to reach a given amount. His aunt decides to write a function to describe her way of thinking about the money in Marco's function
Write the function that the aunt would create. Let T = total amount of money in the account, and let m= number of months.

Answer 1

T = 25 +25m

Explanation:

Marco's aunt wants a function T that tells the total amount in Marco's account after m months when he starts with $25 and adds $25 per month.

Account balance

The balance in the account will be the sum of the initial amount ($25) and the amount added after m months. Marco adds $25 per month, so the amount added after m months is 25m.

The total amount in the account is ...

T = 25 +25m
