Inessa05 [86]
I totally forgot that I am having meeting at my work place. All of sudden, I remembered that meeting through a hint given by my colleague while having discussion about our project work. I have to present a topic which I didn't prepare yet. Meeting is at 1.15pm. OMG! It's already 12.30 pm. Within few minutes I went to the meeting place with my topic. When I entered the meeting hall, the time was 12.53pm. I was happy to know that I arrived 22 minutes earlier.

Yuliya22 [10]
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 <span>$1,280 in her saving's account and each week she and her parents deposit $130 to the account, with </span>n representing the number of weeks, we can model the situation as follows:
f(n)=1280+130n
