Question

Hannah is saving money for a car. She earns $160 each week working part time after school and on the weekends at Papa's Pizza. Hannah currently has $1,280 in savings. Her parents put $50 in her savings account each week and she saves one-half of her paycheck each week. Which expression represents the situation? (n represents the number of weeks)

Answer 1

From the problem we know that Hanna saves one-half of her paycheck each week, so she saves $( \frac{1}{2})(160)= \frac{160}{2} =80$. Also, we know that her parents put $50 in her savings account each week, so the total amount she and her parents put in her saving's account is $80+50=130$.
Since we know that Hanna currently has $1,280 in her saving's account and each week she and her parents deposit $130 to the account, with $n$ representing the number of weeks, we can model the situation as follows:
$f(n)=1280+130n$

Answer 2

Answer:

The answer is A because

Step-by-step explanation:

1,280 in savings

160n

2

Hannah saves each week

50n parents put in savings each week

thus,

1,280 + 160n/2+ 50n

1,280 + 80n + 50n

1280 + 130n

You really have to think this one through all the way.  All the other answer choices are steps in finding the answer
