Final answer:
The correct equation representing the relationship between the dollar amount in Adya's bank account and the number of weeks she saves is A = 60 + 20w, where 'A' is the account balance and 'w' is the number of weeks.
Step-by-step explanation:
We are looking to write an equation that represents the relationship between the dollar amount Adya has in her bank account (A) and the number of weeks she has been saving (w). Starting with $60 in her bank account, she deposits $20 each week. If we compare this to Example 12.4, we can see that the starting amount is similar to a y-intercept, which is the amount of money Adya has before she starts depositing her earnings from babysitting. In this case, it's $60. Each weekly deposit acts as the slope of the linear equation, which is the consistent amount added each week, in this case, $20. Therefore, the equation that represents this relationship is A = 60 + 20w, where A is the total amount in the bank account and w is the number of weeks she deposits money.
