Question

You start a savings account with $200 and save $30 each month. Write a rule to represent the amount of money you invest into your savings account as an arithmetic sequence. how much money will you have invested after 12 months

Answer 1

Rule (where m is months, and t is total saved): 200 + 30m = t

After 12 months: $560

Explanation:

So, we start with $200, and we save $30 each month. Let's call 'month' M.

And we can just use t to stand for total

The arithmetic rule would be: 200 + 30m = t

Alrighty, let's plug in 12 for our m value

200 + 30(12) = t

200 + 360 = t

t = $560
