Answer 1

Answer: Haylee has $2000 in her savings account after week 25.

Step-by-step explanation:

Given: Haylee opened her savings account with $440 in week 1.

Each week after this, she deposited $65 in her account.

It is an arithmetic series, where $a_1=440$ and d=65

to find the amount in bank after week 25 , put the values in the formula

$a_n=a_1+d(n-1)$ with n=25

$a_{25}=440+65(25-1)\\\Rightarrow\ a_{25}=440+65(24)\\\Rightarrow\ a_{25}=440+1560=2000$

Hence, Haylee has $2000 in her savings account after week 25.
