Question

Carson has $450 in his bank account and deposits $70 per month out of his babysitting money. Construct a linear function that models Carson’s bank balance for any given month.

Answer 1

Answer:

$y=450+70x$

Step-by-step explanation:

Let the number of months = x

It is given that,

Carson deposits $70 each month and has $450 in his bank account.

So, the initial deposit is $450 and monthly deposit is 40x.

Let Carson's bank balance = y (in dollars).

Thus, the linear function representing the bank balance is,

$y=450+70x$
