You're supposed to subtract?
Hang on one moment.
Alright man.
It's A.
Correct. Alright this one. Sorry for asking so many questions! You made two deposits to your bank account this month. One deposit was $24.61, and the second deposit was $16.49. Your balance at the end of the month is $72.31, and you made no withdrawals. Write and evaluate an expression for your balance at the beginning of the month. A $72.31 + ($24.61 – $16.49); $80.43 B $72.31 – ($24.61 – $16.49); $64.19 C $72.31 – $24.61 – $16.49; $31.21 D $72.31 + $24.61 + $16.49; $113.41
That's a long one....hang on.
A little help, @Kitt020912 ?
Dude ,why are you cheating ?
I'm not. He's actually helping me tbh.
I didn't know that.. She*
Yeah hard to believe I'm helping for once in my OS life.
I'm not good with word problems, sorry. :l
I can't see any help here .. you should learn how to answer the questions by yourself .
If you know the setup, then I can help you from there.
Eyad, why aren't you an ambassador? You act like one sometimes. c:
Anyway , Since there is no withdraw if you subtract the two deposits from the balance at the end of the month, you'll have the beginning balance.
@Kitt020912 i'm just using logic :)
@VinnyT Hint over there ^
